There, that worked. Lets check R2

RP/0/RSP0/CPU0:R2#ping vrf R3R4 10.1.24.4

Fri Apr 20 01:56:49.742 UTC

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.1.24.4, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms

Ok, we have connectivity. Now we can get OSPF working between the PE and the

CEs.

First up, PE1

We need to specify what we want to call our OSPF process, here I just used

R3R4

RP/0/RSP0/CPU0:R1(config)#router ospf R3R4

Now we need to configure OSPF for the VRF

RP/0/RSP0/CPU0:R1(config-ospf)# vrf R3R4

Now for the area

RP/0/RSP0/CPU0:R1(config-ospf-vrf)# area 0

And then place the interfaces that we want in area 0

RP/0/RSP0/CPU0:R1(config-ospf-vrf-ar)# interface GigabitEthernet0/1/0/19

And commit our changes ( I just hit CTRL-Z)

Uncommitted changes found, commit them before exiting(yes/no/cancel)?

[cancel]:yes

RP/0/RSP0/CPU0:R1#

Ok, that is PE1 – now for PE2

RP/0/RSP0/CPU0:R2#conf t
