Hello everyone,
I've got a config I'd like some input on -
I've got a ISR currently being used to tie in a MPLS for voice traffic into a office location. It's got two interfaces currently used.
interface Loopback1
ip address 10.16.145.10 255.255.255.255
!
interface GigabitEthernet0/0/0
description Level 3
ip address 198.xxx.xxx.6 255.255.255.252
ip flow monitor Orion input
ip flow monitor Orion output
media-type rj45
speed 100
no negotiation auto
!
interface GigabitEthernet0/0/1
description TO SWT-CORE
bandwidth 768000
ip address 10.255.255.105 255.255.255.252
no ip proxy-arp
ip pim sparse-dense-mode
ip flow monitor Orion input
ip flow monitor Orion output
ip tcp adjust-mss 1400
negotiation auto
service-policy input DSCP-MARKUP
!
interface GigabitEthernet0/0/2
no ip address
ip flow monitor-Orion input
ip flow monitor -Orion output
shutdown
negotiation auto
It does OSPF back to the core switches via G0/0/1.
I want to add an ISPs LAN block to 0/0/2 then use a sub interface for the WAN block back to down stream routers.
What I think must be done -
Config G0/0/1 as a port channel.
It's IP will be OSPF neighbor and redistribute the MPLS routes into the core. Then have the ISP block as a sub interface like below -
interface Port-channel1.120
encapsulation dot1Q 120
ip address 10.8.120.2 255.255.255.0
ip pim sparse-dense-mode
ip flow monitor Monitor-FNF input
ip flow monitor Monitor-FNF output
service-policy input DSCP-MARKUP

interface Port-channel1.999

encapsulation dot1Q 999
ip address 12.xxx.xxx.xxx 255.255.255.248

interface GigabitEthernet0/0/0
description ATT Internet -
ip address 12.xxx.xxx.26 255.255.255.252

ip flow monitor Monitor-FNF input
ip flow monitor Monitor-FNF output

shutdown
media-type sfp
speed 1000
no negotiation auto
!
interface GigabitEthernet0/0/1
description Internal Network Portchannel
no ip address

Thoughts? Would the PO not be needed here?
