Im redistributing static routes to EIGRP.Is it possible to block the external EIGRP route update?so that other sites will not receive unneccesary routes.If possible,how can i do that?

Re: blocking eigrp update

Hello,

You can block specific routes to neighbors using interface-specific distribute-lists.

For example, if you want to block route 10.0.0.0/24 (which is a redistributed static) from being sent over interface eth0, do the following:

access-list 10 permit 10.0.0.0 0.0.0.255

!

router eigrp 20

distribute-list 10 out Ethernet0

You can use this for both external and internal routes.

Hope that helps - pls rate the post if it does.

Whoops... quick correction. The ACL should be:

access-list 10 deny 10.0.0.0 0.0.0.255

access-list 10 permit any any
