Core connectivity issue with Voice

[rohit.kulkarni]

Hi,

We are having connectivity like,

Voice RT(Location A)->Voice RT2(Location B)-> RT connected to Core switches (Location B)

We removed uplink between Core1 and Core2 and at same time Voice calls dropped.

Do we require any additional config on Core switches?

Thx

Hello Rohit,

if the uplinks are L2 trunks you may consider to move to:

RPVTP

or

MST

both uses 802.1W Rapid STP that allow sub-second STP convergence (compare it to up to 50 seconds with traditional STP 802.1d)

a link to both

if the link was a layer3 link you need to review your routing configuration

Hope to help

Giuseppe
