With this topology I can ping R1 to R2 by using IPV6 Add!

I have just rebuild topology to work on IE vol2, lab 7!

Hi,
well if you send me the output of the commands below I can try to help
you...

I'm also very curious to see how you configured the 2 interfaces of the
cat3550 connected to R1 and R3, and the full configuration of the 2 SVIs...
because fallback bridging does not bridge ip.
This is from Cisco website:

"With fallback bridging, you can forward non-IP packets that the switch does
not route between VLAN bridge domains and routed ports"

I replace R2 by 3550 Switch and I create 2 vlan Vlan 10 and Vlan 20! When I
do the same thing on Switch!

Bridge irb

Bridge 1 protocol vlan-bridge

Int vlan 10

 Bridge-group 1

Int vlan 20

 Bridge-group 1

 

R1 and R3 can ping each other!

So I really don't understand what is the problem???

mmmmh I"m doing it all the time.
Can you do on R2 (by the way you don't need to route ip on bridge 2 if you
don't route thru a BVI):

show bridge 1

show bridge 1 group

show interface s0/1/0 irb

show interface s0/2/0 irb

Hi Group!

I have problem about bridge-group that I can't get over!

This is my topology!
R1(se0/1/0)--------(s0/1/0)R2(s0/2/0)-------------(s0/1/0)R3

I want to R2 bridge its S0/1/0 and S0/2/0 so that R1 can ping R3 in the same
subnet! So I configure like this:

R1(config)#int se0/1/0

R1(config-if)#ip add 1.1.1.1 255.255.255.0

R2(config)#bridge irb

R2(config)#bridge 1 protocol ieee

R2(config)#bridge 1 route ip

R2(config)#int se0/1/0

R2(config-if)#bridge-group 1

R2(config)#int se0/20

R2(config-if)#bridge-group 1

R3(config)#int se0/1/0

R3(config-if)#ip add 1.1.1.2 255.255.255.0

But the R1 can not ping R3!

I do not understand why!

Thanks!
