I am working in a very sensative environment so I want to ask questions before I do anything. If I redistribute static routes into eigrp will the gateway of last resort also be redistributed? each site has its own connection to an ISP so I do not want to redistribute static default route. Is it better to redistribute static routes via distribute-list command or route map?
Deny is implicit, no need to add it into the ACL.
Your ACL should look like this
access-list 10 permit 172.23.0.0 0.0.255.255
access-list 10 permit 172.19.0.0 0.0.255.255
Also, make sure to define the metric in the redistribute command
router eigrp x
redistribute static route-map STATICREDIST metric 10000 10 255 1 1500
