vpls configuration on CSR

Level 1

Hello All,

 

I am trying to configure VPLS on the Cisco CSR routers. 

R1(gi1)----(gi1)R2(gi2)----(gi2)R3(gi1)---(gi1)R4(gi2)---(gi2)R5

 

But ping is not working from R1 to R5. BGP session from R2 to R4 is up.

I am not sure what configuration is missing from routers.


r1#ping 100.10.10.5
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 100.10.10.5, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)

 


R2#show mpls forwarding-table
20 No Label lbl-blk-id(1:0) 0 drop
21 No Label lbl-blk-id(1:1) 0 drop

Hi @sachin30720041 ,

 

The VE ID needs to be unique. Change the VE ID on R4 and it should fix the issue.
