Chapter 1 Configuring OSPF
Customizing OSPFv2
Configuring an IP Address Pool for Clustering (OSPFv2 and OSPFv3)
You can assign a range of IPv4 addresses
for the router ID cluster pool if you are using Layer 3 clustering.
To assign
a range of IPv4 addresses
for the router ID cluster pool in Layer 3 clustering for OSPFv2 and
OSPFv3, enter the following command:
:
Defining Static OSPFv2 Neighbors
You need to define static OSPFv2 neighbors to advertise OSPFv2 routes over a point-to-point,
non-broadcast network. This feature lets you broadcast OSPFv2 advertisements across an existing VPN
connection without having to encapsulate the advertisements in a GRE tunnel.
Before you begin, you must create a static route to the OSPFv2 neighbor. See Chapter 1, “Configuring
Static and Default Routes,” for more information about creating static routes.
To define a static OSPFv2 neighbor, perform the following steps:
Detailed Steps
Command Purpose
router-id cluster-pool hostname | A.B.C.D ip_pool
Example:
hostname(config)# ip local pool rpool 1.1.1.1-1.1.1.4
hostname(config)# router ospf 1
hostname(config-rtr)# router-id cluster-pool rpool
hostname(config-rtr)# network 17.5.0.0 255.255.0.0
area 1
hostname(config-rtr)# log-adj-changes
Specifies the router ID cluster pool for Layer 3 clustering.
The cluster-pool keyword enables configuration of an IP
address pool when Layer 3 clustering is configured. The
hostname | A.B.C.D. keyword specifies the OSPF router ID
for this OSPF process. The ip_pool argument specifies the
name of the IP address pool.
Note
If you are using clustering, then you do not need to
specify an IP address pool for the router ID. If you do
not configure an IP address pool, then the ASA uses
the automatically generated router ID.
Command Purpose
Step 1
router ospf process_id
Example:
hostname(config)# router ospf 2
Creates an OSPFv2 routing process and enters router
configuration mode for this OSPFv2 process.
The process_id argument is an internally used identifier for this
routing process and can be any positive integer. This ID does not
have to match the ID on any other device; it is for internal use
only. You can use a maximum of two processes.
Step 2
neighbor addr [ interface if_name ]
Example:
hostname(config-rtr)# neighbor 255.255.0.0
[interface my_interface]
Defines the OSPFv2 neighborhood.
The addr argument is the IP address of the OSPFv2 neighbor. The
if_name argument is the interface used to communicate with the
neighbor. If the OSPF v2neighbor is not on the same network as
any of the directly connected interfaces, you must specify the
interface.
