CAUTION: In this example, the sub-interfaces can also be configured as
point-to-point (P2P) FR sub-interfaces. In this case, it is not necessary to use the fr
map command on point-to-point FR sub-interfaces; however, you need to
configure the same DLCI at both the DCE and DTE sides by using the fr dlci
command. This is an alternative method of configuring bridging over FR.
Network requirements
As shown in Figure
and Ethernet1/2 of a router respectively. Configure a bridge set and enable routing
of traffic passing each interface in the bridge set.
