I have ethernet handoff link between two 2811 routers. following is the topology.
These 2811s are equiped with Nm16 switch card.
Trunk is configured on ethernet interfaces. There are 2 VLANs: VLAN1 and VLAN 110. VLN1 is management and VLAN110 is DATA.
My problem is when e1 goes down and comes up, VLAN1 goes into forwarding state in trunk. But VLAn110 stucks up.
VLAn 110 doesnt goes in forwarding state. When ever I manually shut/no shut respective trunk interfaces VLAn 110 goes in forwarding state.
Why this is happening? Can anybody throw somelight on this?
