The customer is looking for failover link support for primary link on MPLS. WE are looking for ISDN and ethernet as a backup medium. Kindly see if the same can work.I have advanced IP services IOS on the router.
My query is that for the backup, do I need to involve the MPLS service provider to provide backup or can I provide backup link without the help of MPLS service provider.
Thanks in advance
So now you can create a dialer group for your clinet on your ras. When the primary link fails the isdn will be intiated and the call comes to the ras after that it will be autheticated and foradd to the LNS and a L2 session will be intiatd for the same. Now you ca create a pool for the clinet on the ras when it gets authenticated it will get the ip from the pool and there shold be a loopback which is part of the vrf. In this way the communication will be possible. If you need configs please let me know i can forward the configs too Or you want to try at your end first.
