CE2(config-if)#ip add 10.1.34.4 255.255.255.0

CE2(config-if)#int l0

CE2(config-if)#ip add 10.4.4.4 255.255.255.255

CE2(config-if)#router ospf 1

CE2(config-router)#net 10.0.0.0 0.255.255.255 a 0

CE2(config-router)#

Ok, now time for the PE routers.

PE1:

First, lets reset the interface to all its defaults:

RP/0/RSP0/CPU0:PE1(config)#default interface g0/1/0/19

RP/0/RSP0/CPU0:PE1(config)#commit

Now PE2:

RP/0/RSP0/CPU0:PE2(config)#default interface g0/1/0/19

RP/0/RSP0/CPU0:PE2(config)#commit

Now, lets kill our OSPF sessions. On both routers:

PE1:

RP/0/RSP0/CPU0:PE1(config)#no router ospf 100

RP/0/RSP0/CPU0:PE1(config)#commit

PE2:

RP/0/RSP0/CPU0:PE2(config)#no router ospf 100

RP/0/RSP0/CPU0:PE2(config)#commit

OK, now we can build out L2VPN cross-connects.

Fist up, we need to get to the L2VPN configuration

RP/0/RSP0/CPU0:PE1(config)#l2vpn

Now to configure our X-Connect group

RP/0/RSP0/CPU0:PE1(config-l2vpn)#xconnect group R3R4

And our Point-to-Point settings

RP/0/RSP0/CPU0:PE1(config-l2vpn-xc)#p2p R3_to_R4

Place the interface in the P2P group R3_to_R4

RP/0/RSP0/CPU0:PE1(config-l2vpn-xc-p2p)#interface g0/1/0/19

Specify our Neighbor for this with a pseudowire ID (think of it as a circuit

ID) and then commit our changes

RP/0/RSP0/CPU0:PE1(config-l2vpn-xc-p2p)#neighbor 150.2.2.2 pw-id 304

RP/0/RSP0/CPU0:PE1(config-l2vpn-xc-p2p-pw)#comm

Now, this is unique to our CE devices, we need to specify the speed in order

to get the interfaces up as the CE routers here do not support Gigabit

Ethernet

RP/0/RSP0/CPU0:PE2(config-if)#int g0/1/0/19

RP/0/RSP0/CPU0:PE2(config-if)#spee 100

RP/0/RSP0/CPU0:PE2(config-if)#comm

Now for PE2:

1 2 ... 93 94 95 96 97 98 99 100 101 102 103 104 105
