Implementing OSPF
Command or Action
Step 10 Repeat Step 9 for all neighbors on the interface.
Step 11 exit
Example:
RP/0/RP0/CPU0:router(config-ospf-ar-if)# exit
Step 12 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# interface
GigabitEthernet 0/3/0/1
Step 13
Do one of the following:
• neighbor ip-address [ priority number ] [
poll-interval seconds ][ cost number ] [
database-filter [ all ]]
• neighbor ipv6-link-local-address [ priority number
] [ poll-interval seconds ][ cost number ] [
database-filter [ all ]]
Example:
RP/0/
/CPU0:router(config-ospf-ar)# neighbor 10.34.16.6
or
RP/0/
/CPU0:router(config-ospf-ar)# neighbor
fe80::3203:a0ff:fe9d:f3f
Purpose
—
Enters area configuration mode.
Enters interface configuration mode and associates one or
more interfaces for the area configured in Step 4.
Configures the IPv4 address of OSPF neighbors
interconnecting to nonbroadcast networks.
or
Configures the link-local IPv6 address of OSPFv3
neighbors.
Routing Configuration Guide for Cisco NCS 6000 Series Routers, IOS XR Release 6.4.x
Configuring Neighbors for Nonbroadcast Networks
incoming and outgoing LSAs are filtered. Use with
extreme caution since filtering may cause the routing
topology to be seen as entirely different between two
neighbors, resulting in black-holing of data traffic or
routing loops.
• In this example, the interface inherits the
nonbroadcast network type and the hello and dead
intervals from the areas because the values are not
set at the interface level.
• The ipv6-link-local-address argument must be in
the form documented in RFC 2373 in which the
address is specified in hexadecimal using 16-bit
values between colons.
• The priority keyword notifies the router that this
neighbor is eligible to become a DR or BDR. The
priority value should match the actual priority setting
on the neighbor router. The neighbor priority default
value is zero. This keyword does not apply to
point-to-multipoint interfaces.
• The poll-interval keyword does not apply to
point-to-multipoint interfaces. RFC 1247 recommends
that this value be much larger than the hello interval.
The default is 120 seconds (2 minutes).
• Neighbors with no specific cost configured assumes
the cost of the interface, based on the cost command.
On point-to-multipoint interfaces, cost number is
the only keyword and argument combination that
works. The cost keyword does not apply to NBMA
networks.
