And on PE2:

RP/0/RSP0/CPU0:R2(config)#router ospf R3R4

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

RP/0/RSP0/CPU0:R2(config-ospf-vrf)# redistribute /jointfilesconvert/356165/bgp 1

RP/0/RSP0/CPU0:R2(config-ospf-vrf)# ^Z

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

[cancel]:yes

RP/0/RSP0/CPU0:R2#

Ok, lets check CE1 for routes to CE2 now

CE1#sh ip route

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default, U - per-user static

route

o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

10.0.0.0/8 is variably subnetted, 4 subnets, 2 masks

C 10.1.13.0/24 is directly connected, FastEthernet0/0

C 10.3.3.3/32 is directly connected, Loopback0

O IA 10.4.4.4/32 [110/12] via 10.1.13.1, 00:00:51, FastEthernet0/0

O IA 10.1.24.0/24 [110/11] via 10.1.13.1, 00:00:51, FastEthernet0/0

CE1#

There they are, lets do a PING

CE1#ping 10.4.4.4 so l0

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.4.4.4, timeout is 2 seconds:

Packet sent with a source address of 10.3.3.3

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms

CE1#

Nice, we can PING!

Now, one other thing that you should notice with the CE1 routing table,

routes to CE2 are seen as O IA, OSPF InterArea routes. This is what is

expected when you run the same CE OSPF process ID over a MPLS network – the

BGP will carry the extra attributes creating what is called a Super Backbone.

When we decode the BGP route information using the show /jointfilesconvert/356165/bgp vpnv4 unicast vrf

R3R4 10.1.13.0/24 command, we get the following output - notice the extended

community information, this is where the extra information is carried. We

will actually pull up both 10.1.13.0 and 10.1.14.0 so you can see.
