distribute list change

Netstudent

I have a distribute list in router config mode for EIGRP. This list basically blocks some static routes from being redistributed into eigrp and causing loops.

Now I have to change the access-list that the distribute-list calls to define what to block. I need to add an entry.

My question is, if I clear out this access-list to modify it, is that going to simultaneously kill my distribute-list in EIGRP config mode and cause DUAL to recalculate the topo table and send out an update?

Because if that happens I will get loops to critical servers and that won;t jive.


So I think lesson learned here is use a named ACL for potentially dynamic ACL's????????

ACLs take effect immediately. Perhaps create a new ACL and modify your distribute-list to use the new ACL when you have it ready.... This way you can immediately return to the old ACL if you screw something up. I would recommend scheduling downtime for this if possible.
