Cisco Juniper MVPN

Hi,

I have a Cisco gear cloud. The cisco one uses SSM for mVPN for both default and data MDT. Now I have to intergrate mVPN into a cloud which has Juniper gear, dont know much about Juniper cloud MVPN details, but I have heard that there are interoperability , as SSM is not supported on Juniper. Can anyone explain with aspect to INtra-AS-MVPN & Inter-AS-MVPN?

Thx..

Gaurav,

Juniper does not support SSM for the dafault MDT but they do for the data MDT. For interoperability purposes, you need to go to the lowest common denominator, which is ASM for the default MDT. You can go with SSM for the data MDT though as both Cisco and Juniper support it.

By the way, is that InterAS mVPN or a single AS?

hi hritter

I have a query how can we create data mdt without creating default mdt. For MVPN default mdt is manadatory because it is responsible for MTI.

Shivlu,

The default MDT is definitely required. I was just pointing out that, in a dual vendor network, you could use SSM for the data MDT and ASM for the default MDT.

Re: Cisco Juniper MVPN

Actually I need to pick protocols which is also comfortable for Inter-AS OPtion B environment. Thats why I prefer SSM, as MDT SAFI is very easy way InterAS too.

If I select ASM model for default MDT & SSM for data mdt, then what the prefered model for INterAS mVPN deployment?

Re: Cisco Juniper MVPN

Gaurav,

As far as I know, IOS and JUNOS will not interoperate in an InterAS option 10B context. This is due to some new features required for the support of InterAS mVPN in an option 10B, which are not supported by JUNOS. These features are the connector attributes, the MDT SAFI and the RPF Vector and are documented in the below URL. But as Mohamed mentioned option 10A would not be an issue though and it is the simplest by far.

Re: Cisco Juniper MVPN

Hi,

For (Inter-AS Mvpn) , I would choose Option (A), its the easiest simplified vrf to vrf connectivity between PEs , this unless Mr. Harold has another suggestion.
