EoMPLS Question

Unanswered Question
Jul 24th, 2007

Does anyone know if you can configure EoMPLS on an SVI interface if you have the ES20 cards facing the core and the x6724 cards facing the CPE. The 7600 documentation for 12.2SR says you have to have an OSM or Enhanced Flex Wan module facing the core but this was befoere the ES20 cards came out. Below is an example of what I would like to do.

CE--->(x6724--7600--ES20)---core---(ES20---7600---x6724)--->BRAS

7600 facing the CE.

vlan 10 name voice

!

vlan 20 name video

!

vlan 100 name data

!

int gig4/1

switchport

switchport trunk ecap dot1q

sw mode trunk

switcport trunk allowed vlan 10,20,100

!

int vlan 10

ip add 10.10.1.1 255.255.255.0

!

int vlan 20

ip add 10.20.1.1 255.255.255.0

!

int vlan 100

xconnect 10.10.100.101 100 encapsulation mpls

I have this problem too.

Hi,

This EoMPLS should work with all the Ethernet cards. The OSM/Flexwan module facing the MPLS core restriction was only for VPLS. I think VPLS is supported on ES20 line cards.

We tried this with x6724s facing the core and x6748s facing the CE and it didn't work and was told by TAC that we needed the OSM or Enhanced flex wan module. I'm hoping the ES20 card has the same functionality as the OSM or Enhanced flex wan. In reading over the data sheet last night it appears that it supports all the MPLS/AToM features that the OSM modules supports. I'm thinking if it doesn't work with an SVI it should work with sub-interfaces.
