Hi, Just want to ask your inputs on below scenario.
Sample TOpology:
SiteA ----(ProviderA)-----(ProviderB)-----SiteB
Site a sending unicast and multicast traffic.
Issue - Traffic not being sent to SW2 pointing Site B. (primary traffic is multicast)
#sh int g1/1
30 second input rate 1179 bits/sec, 1283 packets/sec
30 second output rate 0 bits/sec, 0 packets/sec
- At first SiteA sending untagged frames to Partner to Provider to Site B which has no issue. but when they tried sending tagged frames to Site B, seems like switch not sending any traffic to Site B.
Q: Do you think it affects the frames being sent to site B? Since QinQ is applied on SW01, additional header has been inserted so i think C-Tag will not affect this?
- In the scenario of flooding method like unicast,multicast & broadcast, does the above mentioned scenario affect the behaviour of the flooding mechanism?
#sh int g1/1
Received 0 broadcasts (0 IP multicasts) <- based on the interface output of switch2, broadcast and multicast is not increasing. (Note that the primary traffic of this list is multicast.)
- From RT VC statistics(Pointing to SW2)
VC statistics:
transit packet totals: receive 23901162939, send 111031102 <- Increasing
transit byte totals: receive 32752316549739, send 14447377651 <- Increasing
transit packet drops: receive 4417, seq error 0, send 0 <- Not Increasing
- If MTU take place, both RTR and SW configured more than the default value.
- From show interface what is the difference between 2 multicast output?
Received 0 broadcasts (0 IP multicasts) <--- Multicast here?
0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 watchdog, 19625 multicast, 0 pause input <--- Multicast here?
What verification do you think should be done? Any idea?
Thanks
