One way iv got this to work is by creating a BVI2 instance +bridge irb in the same 100.100.100.x subnet on each r1/r2/r6/r9
Would this satisfy the requirement? Seems by merely bridging from r1 to r9 bb1 & bb3 can't talk, the config below was the same as Joe's detailed solution guide On 13 October 2012 14:36, Tony Singh <[email protected]> wrote: > > Hi > > This is from V1 lab 7.4 > > *Topology* > BB1 > VLAN100 > R1 VLAN12 > R2 > FR P2P > R6 bridged to R9 > VLAN300 > BB3 > > Goal is to ping from BB1 100.100.100.100/24 to BB3 100.100.100.250/24 > > I can see arp on R1 & R9 for both BB1 & BB3 f0/0 interfaces but I cant get > ping to run from either end... > > Because this task bridges 3 vlan domains iv checked the relevant > switchport configs are ok hence would not be getting the mac addresses for > each end of the bb's on r1/r9 (although they do time out a bit) > > Debug shows the ar coming in at either r1 r r9 ends > > r1 > *Oct 13 10:17:59.847: IP ARP: rcvd req src 100.100.100.100 000d.bd31.0460, > dst 100.100.100.250 FastEthernet0/1 > > r9 > *Oct 13 12:41:07.002: IP ARP: rcvd req src 100.100.100.250 000f.8fdd.5740, > dst 100.100.100.100 FastEthernet0/0 > > Spanning tree bridge instance 2 is running and agree on R6 as root.... > > configs below > > r1 > bridge irb > bridge 2 protocol ieee > bridge 2 route ip > int f0/0 > bridge-group 2 > int f0/1 > bridge-group 2 > > > r2 > bridge 2 protocol ieee > int f0/0 > bridge-group 2 > int s0/2/1.206 > bridge-group 2 > > r6 > bridge 2 protocol ieee > int s0/1/0.602 > bridge-group 2 > int s0/2/0 > bridge-group 2 > > r9 > bridge irb > bridge 2 protocol ieee > bridge 2 route ip > int s0/2/0 > bridge-group 2 > int f0/0 > bridge-group 2 > > > can you see what's wrong? > > > > > _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
