Hi All,
Please help me with below problem, what I am doing wrong?
Appreciate your help
Thanks
Khurram.
--------------------------------------------------------------------------
Topology
PC1(134.177.1.1)--eth0/0(Router3)Se0/0----Se0(Router1)Eth0---PC2(134.177.1.2)
Router3 -- CRB
Router1 -- Transparent Briding (no ip routing)
Task
***************
Ping from PC1 to PC2
Problem:
********
I configured R3 for CRB. I included eth0/0 and se0/0 in bridge-group 1.
I want to bridge IP on eth0/0 and se0/0 and route on rest of the interfaces
in
R3. As soon as I write command "bridge-group 1 route ip" R3 bridged
interfaces
also immediately stops bridging and learnig macs. When I do "show bridge"
after
putting command "bridge 1 route ip", all MAC entries in the forwarding table
vanishes. When I remove the command all mac entries shows back (router
starts learning).
See the problem in below shapshot:
first router is learning fine:
R3#show bridge
Total of 300 station blocks, 296 free
Codes: P - permanent, S - self
Bridge Group 1:
Address Action Interface Age RX count TX count
00a0.cc3f.8184 forward Serial0/0 0 531 530
00a0.cc5f.6e4a forward Ethernet0/0 4 1 0
0090.2797.b68d forward Ethernet0/0 0 533 531
00b0.d070.cc74 forward Ethernet0/0 0 5 0
R3#
Now when I put command "bridge 1 route ip" and "bridge 1 bridge ip" the
bridged
interfaces stops learning macs (ping stops!!!!)
