6pe Configuration

[sachin30720041]

Hello All,

I am trying to configure 6PE. Routes got exchanged but ping is not working.

R1and R5 are CE devices.

R2 and R4 are PE devices.

R1--(ospfv3)--R2---(ldp+ospf)--R3----(ldp+ospf)--R4--(ospfv3)--R5

R1,R2 and R4,R5 are running ospfv3.

Bgp session between R2 and R4 is up. 

ldp+ospf is running between R2,R3 and R4.

1111::1 is loopback on R1 and 5555::5 is loopback on R5.

on R5:

R5#ping 1111::1 source 5555::5

.....
Success rate is 0 percent (0/5)

R5# show ipv6 route ospf

OE2 1111::1/128 [110/1]
via FE80::C804:4CFF:FEC2:1D, Ethernet1/1
O 4444::4/128 [110/10]
via FE80::C804:4CFF:FEC2:1D, Ethernet1/1

Below is the configuration on R1,R2,R3,R4 and R5.

Hi @sachin30720041 ,

LDP is not configured on R3. You need an LSP to be signaled from R2 to R4 and vice versa for 6PE to work.

Thank you two. I have learnd a new command.

mpls ldp autoconfig
