Does it have to be frame relay? What you need here is PPP Half-bridging. http://www.cisco.com/en/US/tech/tk713/tk507/technologies_configuration_example09186a0080093c80.shtml Your other choice would be to use Integrated Routing and Bridging. http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a00800ca767.html#wp1041949 > Router B: > FE 0/0: no ip - bridged ethernet connection - bridge-group 2 > S0/0: encapsulation frame relay > S0/0.1 ptp: 172.20.0.2/30 dlci 100 bridge-group 1 > S0/0.2 ptp: unnumbered - bridged to ethernet bridge-group 2 > You need to disable IP routing here because IOS does not bridge IP just because no IP addresses are applied to an interface. > PC: > ETH: 5.6.7.9/30 connected to Router B FE 0/0. > > > My serial and sub interfaces come up.
