Changing the root bridge when you have already configured PAgP

[johnmcgrath29]

I don't seem to be able to configure the Root Bridge after I have configured PAgP do I have to roll that Back and configure Root Then apply PAgP or is there away to do it without rolling back PAgP ???

Hi John,

Configuring PAgP should not have anything to do with Root Bridge.

Root Bridge is usually configured in global config.

Sample config:

Spanning-tree vlan 10-50 root primary
