MPLS AToM Section

In this lab, we will configure MPLS AToM on R5 and R7 to provide layer 2 connectivity to R9 and R11 as if they were directly connected.


R5 Config

pseudowire-class AS3-AS4
 encapsulation mpls
!
interface FastEthernet1/1
 xconnect 7.7.7.7 34 pw-class AS3-AS4

R7 Config

pseudowire-class AS3-AS4
 encapsulation mpls
!
interface FastEthernet1/1
 xconnect 5.5.5.5 34 pw-class AS3-AS4

R9 Config

interface FastEthernet0/0
 ip address 192.168.119.9 255.255.255.0

R11 Config

interface FastEthernet0/0
 ip address 192.168.119.11 255.255.255.0
