RedundantBGP Route Reflectors cluster-IDs

Consider the following topology:

Would it make more sense to use the same or different cluster-IDs? My understanding as of right now is different cluster IDs.

Current config of RR1:

RR1#show run | s bgp router bgp 2 bgp log-neighbor-changes neighbor 4.4.4.4 remote-as 2 neighbor 4.4.4.4 update-source Loopback0 neighbor 4.4.4.4 route-reflector-client neighbor 5.5.5.5 remote-as 2 neighbor 5.5.5.5 update-source Loopback0 neighbor 5.5.5.5 route-reflector-client neighbor 6.6.6.6 remote-as 2 neighbor 6.6.6.6 update-source Loopback0 neighbor 6.6.6.6 route-reflector-client neighbor 7.7.7.7 remote-as 2 neighbor 7.7.7.7 update-source Loopback0 neighbor 7.7.7.7 route-reflector-client neighbor 12.12.12.12 remote-as 2 neighbor 12.12.12.12 update-source Loopback0 

Each client has 1 peering to each RR.

SFP+ modules - I learned something today

Of course you can plug an SFP in to an SFP+ port, everyone knows that. Today I learned you can can plug (maybe only under certain circumstances?) a 10Gbit SFP+ in to a 10Gbit SPF+ port, OR in to a 1Gbit SFP port. You can even force the speed of a 10Gbit SFP+ port to 1Gbit, and link up with a 1Gbit SFP.

Sorry if this is old news, it got me out of a bind today, didn't know it was possible. I'm used to optics being capable of only one speed.



Changing jobs from Fiber Field Engineer to Coax. Would I pick it up easily?

My current job is currently underpaying me greatly, so I decided to switch jobs and I found a position with a higher negotiable salary. I've been working with Optical fiber for around 2 years now and have great experience with all the processes involved to get the fiber connected in the exchange.

New job I found works with Fiber coax hybrid in metro areas and in apartment buildings. I haven't ever seen the process involved to get that running but I have sometimes seen the active hybrid fiber equipment in the field.

Would I pick up the work easily? I'm worried that it's going to take me awhile to but since I've been working with fiber for so long, they assume I'm a professional. Is there anything I should know before starting the job?

(I've already negotiated my salary so I don't want to disappoint them)

Is it better to have router and modem separate?

Recently been experiencing some problems with my with and decided to buy a new router, however it didn’t work as expected so I’ve decided to return it and this time I’ve order a router and a modem separate does it make a difference?



Media Converters Suck

Media converters suck. I have a lot of networks with over 100 meters between ROuters/MDFS and IDFS, and my engineering team seems to love employing these god awful devices that break at an ungodly hour multiple times a week, at this point the number of media converters we have deployed is just an asinine, and unsustanible amount, I am curious if there are better options for converting between fiber and copper than these devices that we could start deploying in an attempt to phase out media converters, and make our networks more reliable. I am fairly new to the infrastructure side of networking, but have suggested using SFPs as opposed to media converters, and my engineering team shot that down, so I am curious if there are any other devices/methods that could be employed (some sites have upwards of 50 to 100 media converters) .

I am reletively new to the infrastructure side of networking, but it seems the common consensus is media converters are the devil, and having to send out an On call employee to swap them at 3 am is not cost effective.

Managers Asking About Incompetent Co Worker

Hi,

I've been working at this company for a year now and I have a very, very bad co worker, let's call him Bob, who should've been fired a long time ago, but due to corporate structure (our main office and managers are across country), a lack of accountability, an organizational split where our old boss was going to fire him but dumped him onto someone else, and me picking up his slack, he's managed to survive for the past year.

Bob has been a junior engineering for over 10 years when he should probably be a technician. He is the least technical member of our group, and actively avoids work, which means I've been doing a lot of his job for him for the past year. I'm convinced if it weren't for me, he finally might have gotten noticed and fired. From November to Feb of this past year, he had a habit of coming in two hours late and only two days a week (he would "work" from home), which he got away with because we didn't have any supervision. Bob and I work in operations and often times we are the only ones on shift. However, Bob let's me do all the work by actively ignoring requests or doing a piss poor job addressing alerts. Often times he leaves the room when shit breaks and it's something he doesn't know how to handle, which leaves me with the bulk of the work while he watches youtube for 5-6 hours during his 8 hour shift. I've never actively confronted Bob on his work ethic or behaviors, but I've encouraged him to be more pro-active and to investigate issues deeper before writing them off. I've also done my best to answer any questions he has had and have never withheld any knowledge or information from him regarding our job. I know people exaggerate when talking about bad co-workers, but I'm not exaggerating here.

Bob and I also don't get along. I think he's a shitty person and quite frankly, a bitch. He probably thinks I'm a hard ass who takes my job too seriously.

I was fine ignoring him, picking up his slack when needed, and never complained to management about him because I wanted to be bigger person and sometimes complaining does you no good. Having said that, in the past two months, our manager has asked me questions about him, and the VP of our department has started asking me questions about him and his work ethic. I didn't really let on what was going on, but mentioned we might need more leadership in our office, and when our VP, who is the kind of guy who has zero tolerance for bullshit, asked me questions about him, I did my best to say good things about him because as much as I hate him and don't like working with him, I don't want to jeopardize another man's livelihood.

Should I tell my managers the truth?



[Question] Looking for a dual WAN router for my office. Looking at the Cisco RV345

Hi all. I'm searching for a router that supports dual WAN balancing with VPN and firewall features.

What I was able to find is the Cisco RV345 which has all those features, but I'd like one to have also WIFI connection.

My company has about 20 employees and we depend on having a reliable internet connection, that's why I want the dual WAN thing.

Does anybody here have experience with this router or know an alternative that's good and reliable? How about one with these features and also wifi?

Thanks!
