[j-nsp] Juniper M20 <--> Cisco 5300

[Bosco Sachanandani]

Hi All

I have a configuration query, actually I want to know if anyone has done this or can re-direct me to a sample config.

The requirement is to provide ISDN backup to leased lines. All our leased lines terminate on a Juniper Networks M20 router. For ISDN backup we have a Cisco AS5300 connected to our GSM MSC. The network is something like this:

M20 City A --ibgp----> M20 City B ----leased line----> Customer A 
				   |
				   |
			incase leased line fails
				   |
				   |
				ibgp
				   |
				   |
				   V
				AS5300 ----------ISDN --------> Customer A

First of all, has anyone everydone this config and got it working??

There are route distinguishers configured for the customers routes and VRFs are used at each of the M20 and AS5300 boxes. 

Well IBGP comes up correctly but somehow when the leased line fails, the customer's routes do not get exported into the Cisco. The ISDN line works fine.

Any clues would be great..

thanks
Bosco
