Step 4
rewrite ingress tag pop 1 symmetric
Example:
Router(config-if-srv)#rewrite ingress tag pop
1 symmetric
Specify that encapsulation modification to occur on packets at
ingress.
• pop 1—Pop (remove) the outermost tag.
• symmetric—Configure the packet to undergo the reverse of
the ingress action at egress. If a tag is popped at ingress, it is
pushed (added) at egress.
Note Although the symmetric keyword appears to be optional,
you must enter it for rewrite to function correctly.
Step 5
xconnect ip address service-instance-number
encapsulation mpls
Example:
Router(config-if-srv)#xconnect 192.168.1.8
101 encapsulation mpls
Configure cross-connect pseudowire by specifying the IP address
of remote peer and the virtual circuit ID.
