secondary ip and ISDN

1. I have a cisco isdn-router with primary-ip: PA and secondary-ip: PB configured for its ethertnet0.

2. I should configure the BRI0 as "ip address unnumbered ethernet0", (no transitnet?).

Question:

How can I configure the bri0 (dialer map or dialer profile) to two remote-site, when remoteA should use PA and remoteB PB as routeaddress ?

(Problem: by isdn callingout(unnumbered ether0) can ciscorouter only use its primaryaddress?

Can you give me a sampleconfig.

Re: secondary ip and ISDN

You can only use ip addreess unnumbered on the primary address of any

interface.

If your scenario requires you to have two different address

then creat two loopback interfaces with two address and

use ip address lo 0 for dialer 0 and ip address lo 1 for dialer 1

I dont see problem dialing the two site with the same interface

address being used for unnumbered interfaces.
