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?
