I'm trying to ensure I've got the basic understanding of Mobile IP down...
I've got a network that is running OSPF between all of the routers, which
I've verified end-to-end IP connectivity. Here's the highly simplified
network:
E0/0 - Router1 ----- OSPF NETWORK ----- Router 8 - E0/0
Now, here's the requirement:
Task: Support users who relocate from Router 1 to Router 8 without
requiring them to change their IP addresses. Ensure only the users from
E0/0 (network 10.1.1.0/24) are allowed to roam on Router 8's E0/0 interface.
Assuming all routing is working correctly before making any changes (e.g.,
Router 1 can ping Router 8's E0/0 address and vice versa), I believe the
following provides the minimum mobile IP commands required to meet this
task.
Router 1:
interface Ethernet0/0
ip address 10.1.1.1 255.255.255.0
!
router mobile
!
router ospf 1
redistribute mobile metric 100 subnets
!
ip mobile home-agent
Router 8:
interface Ethernet0/0
ip address 172.16.1.1 255.255.255.0
ip mobile arp access-group 1
!
router mobile
!
router ospf 1
redistribute mobile metric 100 subnets
!
ip mobile foreign-agent
!
access-list 1 permit 10.1.1.0 0.0.0.255
So, would this be enough to meet the requirement as stated? If I attached a
PC to Router 8's Ethernet0/0 interface with IP address of 10.1.1.2, should I
expect this PC to be able to ping 10.1.1.1? What changes in the routing
tables should one see if this is working correctly?
TIA!!!
