Thanks for the reply. Let me make sure I understand this.
So, for example, if I want to make anything destined for network
10.0.0.0 to go to next hop 11.0.0.1 but let packets for all other
destinations to use the routing table, I will not need a second permit
statement.
access-list 1 permit 10.0.0.0 0.255.255.255
!
route-map MYMAP permit 10
match ip address 1
set ip next-hop 11.0.0.1
!
ip local policy route-map MYMAP
However, in the following example, I will need a second permit
statement if I want to allow any other routes not explicitly mentioned
in the route-map.
access-list 1 permit 10.0.0.0 0.255.255.255
!
route-map MYMAP permit 10
match ip address 1
!
router rip
network 10.0.0.0
!
router ospf 1
redistribute rip subnets route-map MYMAP
!
Is this correct?
