[c-nsp] L2VPN between ASR920 and Juniper

[Adam Vitkovsky]

Hi Alireza,

This is what I have found :
Interoperability between Cisco and Juniper in L2vpn with vc type 4, CSCuq28998

Symptom:
All VC went down after the IOS upgrade on the router (with the last error: Imposition VLAN rewrite capability mismatch with peer)

o Old image: 12.2(33)SRD3
o New Image: 15.2(4)S4a

Conditions:
VC type 4 negotiation

Workaround:
- configure VC type 5 between the routers (configured on Juniper side)
- configuring or using no-control-word command on Juniper router


Last Modified:
Aug 26,2014

Status:
Terminated

Severity:
2 Severe

Product:
Cisco 7600 Series Routers
