Hi, I'm trying to enable bridging between a serial interface (ppp encapsulated) and an ethernet on a 2800 router. here's the main config:
bridge irb bridge 1 proto ieee
int se 0/0/0:0 encap ppp bridge-group 1
int e0 bridge-group 1 ip address 192.168.1.1 255.255.255.0
On the other side of the serial connection, there's another router with similar config. Problem is one host on the ethernet of one router cannot reach the other host on the other router.
Is bridging on PPP supported at all?
TIA.
What routes are there?
Hi, as I understand, no routes are required on both routers if bridging works correctly to bridge between the Ethernet and the Serial ports.
Theoretically, there is an RFC for extensions ontop of the original PPP RFC's for bridging on it, but why not just eliminate it from the mix and fall back to stock HDLC on the serial links instead since you control both sides? PPP is going to buy you nothing in this setup.
int ser 0/0/0:0 encaps hdlc
which is the default encapsulation for serial ports on IOS. That'll match countless configs done over time for this setup.
