PE1:

RP/0/RSP0/CPU0:R1#conf t

Lets get to our interface, G0/1/0/19

RP/0/RSP0/CPU0:R1(config)#interface GigabitEthernet0/1/0/19

Now we can assign the VRF of R3R4

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

Configure our IP

RP/0/RSP0/CPU0:R1(config-if)# ipv4 address 10.1.13.1 255.255.255.0

Since this is a 100M link, we will need to hard code it for the GBICs sake.

RP/0/RSP0/CPU0:R1(config-if)# speed 100

And Commit our changes

RP/0/RSP0/CPU0:R1(config-if)#comm

Fri Apr 20 01:48:51.120 UTC

RP/0/RSP0/CPU0:R1(config-if)#

Once that is done, let do PE2 the same way.

PE2:

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

Fri Apr 20 01:48:45.677 UTC

RP/0/RSP0/CPU0:R2(config)#interface GigabitEthernet0/1/0/19

RP/0/RSP0/CPU0:R2(config-if)# vrf R3R4

RP/0/RSP0/CPU0:R2(config-if)# ipv4 address 10.1.24.2 255.255.255.0

RP/0/RSP0/CPU0:R2(config-if)# speed 100

RP/0/RSP0/CPU0:R2(config-if)#commit

Fri Apr 20 01:48:51.059 UTC

RP/0/RSP0/CPU0:R2(config-if)#

Now we can test a ping from PE1 to CE1 and PE2 to CE2.

RP/0/RSP0/CPU0:R1#ping 10.1.13.3

Fri Apr 20 01:57:01.969 UTC

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.1.13.3, timeout is 2 seconds:

UUUUU

Success rate is 0 percent (0/5)

RP/0/RSP0/CPU0:R1#

Hmm, that failed – why? Well, when an interface lives in a VRF, you need to

PING from that VRF. Lets try that again using VRF R3R4

RP/0/RSP0/CPU0:R1#ping vrf R3R4 10.1.13.3

Fri Apr 20 01:57:11.522 UTC

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.1.13.3, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms

1 2 ... 82 83 84 85 86 87 88 89 90 91 92 ... 104 105
