Hey, This is a known issue. Paste from Cisco TAC
https://tools.cisco.com/bugsearch/bug/CSCug42508/?reffering_site=dumpcr As per the description on the above DDTS, the following scenarios are unsupported: 1. When we have EVC XConnect/SVI Based XConnect/RPW - It won’t work when core is SVI Trunk. 2. When we have Port-Based XConnect on the other side - It won’t work when core EVC and BD Tag don't match. - It won’t work when core is SVI Trunk. The workaround to this issue is to: 1. To use EVC in the core side instead of switchport trunk or 2. To use mpls over physical routed port instead of svi. /Peter 2014-06-13 11:04 GMT+02:00 Ulrik Ivers <[email protected]>: > Hi all, > > I'm having a problem getting traffic across an xconnect between a ME3600 > and a ASR9K.
