Isdn backup with MPLS

[moament]

Hi all,

we have a vpn based mpls network, and I want one of our custome rto use ISDN backup to connect to his vpn in case of failure of the main line (SDSL), the problem is how the isdn line will connect to the vpn and the vrf of the customer, is that possible , to treat the isdn or dialup as a interface connected to vrf inside a vpn ?

Thanks & BR

Hi

do clarify where the isdn backup is getting connected ?

is it getting connected to the same PE router where the main link is connected or getting connected to a seperate equipment ?

we did come thru the same kind of situation with 2 diff devices coming in for primary and secondary connecitvity.

The same we have overcome by creating a GRE tunnel between the PE router where the main link was connecting and the customer end router.

At PE router tunnel interface bought in mpls and floating static pointed towards the tunnel interface..
