Hi group,
I'm stuck at this bridging over serial interfaces. real simple layout to test b
ridging:
r3-s0--------s0-r5-s1---------s1-r6
s0 and s1 on r5 are put in bridge-group 1, while r3 and r6 are acting as pc hos
ts to ping each
other. pings never got through, not even able to ping BVI 1 on r5.
But, if i replaced serial interfaces with ethernet intfs as below, r3 and r6 ar
e able to ping each
other and the BVI 2 of r5. what is going on here?
r3-e0--------f0-r5-f1---------f0-r6
r3:
interface Serial0/0
ip address 1.1.1.3 255.0.0.0
clock rate 64000
