The following commands configure an HDLC layer 2 circuit over MPLS between an E Series
router and a remote PE device.
To configure an HDLC layer 2 circuit over MPLS:
Configure a serial or POS interface on the ingress router.
1.
host1(config)#interface serial 3/1:2/1
or
host1(config)#interface pos 4/0
Use one of the following methods to create the HDLC layer 2 circuit over MPLS:
2.
Use the mpls-relay or route interface command without the relay-format ppp
keywords. This command causes the router to signal VC-type HDLC on the LDP
session and use HDLC encapsulation. Use this command syntax if the traffic carried
on the serial or POS interface is any kind of standard HDLC (including PPP) or
Cisco HDLC.
host1(config-if)#mpls-relay 2.2.2.1 1
or
host1(config-if)#route interface tunnel mpls:tunnel-to-pe2 1
Use the mpls-relay or route interface command with the relay-format ppp
keywords. This command causes the router to signal VC-type PPP on the LDP
session and use PPP encapsulation instead of the default VC-type HDLC signaling
and HDLC encapsulation. Use this command syntax if the traffic carried on the
serial or POS interface contains actual PPP packets.
host1(config-if)#mpls-relay 2.2.2.1 1 relay-format ppp
or
host1(config-if)#route interface tunnel mpls:tunnel-to-pe2 1 relay-format ppp
(Optional) Attach an MPLS policy to the HDLC layer 2 circuit by using the mpls
