Here's the topo :
|----------- isl trunk ------- 5500 with
users connected in vlan x & vlan y
3550 -- isl trunk -- 5500 -- vlan x access port ----- 4500 (rtr-A)
|_____ vlan y access port ____ 4500 (rtr-A)
The 3550 is configured with 2 logical interfaces vlan x & vlan y
VTP is not running between the 3550 & its directly connected 5500. VLANS are
locally defined on both devices :
- vlan x & vlan y interface & vlan database (3500)
- vlan x & y (5500)
HSRP is configured on the 3500 for both vlans. Same on the 4500.
No problem whatsoever for vlan x.
interfaces are up, no errors. trunks are up, no errors, no pruning. stp is
Layer 2 connectivity for vlan y seems to be broken between 3500 & 4500. I
cannot ping the vlan y interface of any router (from the other router).
From 4500 I can ping users in vlan y.
From 3550 I cannot ping users in vlan y.
At some time I identify LOTS of output queue drops on the vlan y interface
on the 3550.
Since my troubleshooting sessions seemed to be unsuccessful, I ended up
trying to configure VTP between the 3550 & its locally connected 5500.
This solved it. HSRP messages started to flow smoothly for vlan y & output
queue drops stopped.
Although I solved the problem, I dont know why ... any idea ?
