Hello GS,
Suppose the setup that follows:
R4:
!
interface loopback0
ip address 4.4.4.4 255.255.255.255
!
interface serial0/0
ip address 45.45.45.4 255.255.255.0
!
R5:
!
interface serial0/0
ip address 45.45.45.5 255.255.255.0
!
interface serial0/1
ip address 56.56.56.5 255.255.255.0
!
router ospf 1
network 56.56.56.5 0.0.0.0 area 0
!
R6:
!
interface serial0/1
ip address 56.56.56.6 255.255.255.0
!
router ospf 1
network 56.56.56.6 0.0.0.0 area 0
Now I need to configure ODR between R4 and R5 and I need full reachability.
I see two options:
#1
R5:
!
router odr
!
router ospf 1
network 45.45.45.5 0.0.0.0 area 0
redistribute odr subnets
!
#2
!
R5:
router odr
network 45.45.0.0
!
router ospf 1
redistribute odr subnets
!
I prefer option #2 because I see ODR as any other routing protocol. Do we
have any limitations, or all the commands available under the "router odr"
process are valid and maybe used normally ?
R5(config-router)#?
Router configuration commands:
default Set a command to its defaults
default-metric Set metric of redistributed routes
distance Define an administrative distance
distribute-list Filter networks in routing updates
exit Exit from routing protocol configuration mode
help Description of the interactive help system
maximum-paths Forward packets over multiple paths
neighbor Specify a neighbor router
network Enable routing on an IP network
no Negate a command or set its defaults
passive-interface Suppress routing updates on an interface
redistribute Redistribute information from another routing protocol
timers Adjust routing timers
traffic-share How to compute traffic share over alternate paths
R5(config-router)#
Thanks for reading.
Antonio
