Large distribute-list

wfleenor · ‎10-04-2006

I currently have a 32 distribute-lists on two routers that will grow to 155 unless a method can be found.

Situation:

2 routers with 2 serial interface each sub-interface has two distribute-lists one in and one out. The outward bound list are always the same NATed addys. The inward bound addys are always differnet.

Example:

ip access-list standard ser1.033_ROUTES

permit 192.168.200.15

permit 192.168.200.16

permit 192.168.168.47

permit 192.168.168.48

ip access-list standard ser1.022_ROUTES

permit 192.168.200.27

permit 192.168.200.28

permit 192.168.168.59

permit 192.168.168.60

This is done to control displayed routes on third party buildings where physical access cannot be controled. Is there a better way of controling routes then using 155 DLs?

To prevent other routers from learning one or more routes, you can suppress routes from being advertised in routing updates. Suppressing routes in route updates prevents other routers from learning the interpretation of a particular device of one or more routes.Only way to do this is Distribute list.
