ISDN DDR and Routing Protocols [7:47301]

Hy I have a ISDN Dial up and dont want have any Routing Protocol over it. What is the right access-list, and which features should you Block over the ISDN link. access-list 101 permit icmp 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255 ( or any any ) access-list 101 deny Tcp 0.0.0.0 255.255.255

I don't know which IGP protocols you run on your network (if any)... so this is just a wild guess. If you were running RIP it could trigger the link ... (I would add: access-list 101 deny udp any any eq 520) If you were running OSPF (I would add: access-list 101 deny ospf any any) Pierre-A
