Allied Telesis AT-WR4500 manual Virtual link should be configured on both routers, Neighbor-Id

AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers	103
RouterOS v3 Configuration and User Guide

Property Description

neighbor-id(IP address; default: 0.0.0.0) - specifies router-idof the neighbor

transit-area(name; default: (unknown)) - a non-backbone area the two routers have in common

￿

Virtual links can not be established through stub areas

Example

To add a virtual link with the 10.0.0.201 router through the ex area, do the following:

[admin@AT-WR4562] routing ospf virtual-link> add neighbor-id=10.0.0.201 \ \... transit-area=ex

[admin@AT-WR4562] routing ospf virtual-link> print Flags: X - disabled, I - invalid

#	NEIGHBOR-ID	TRANSIT-AREA
0	10.0.0.201	ex

[admin@AT-WR4562] routing ospf virtual-link>

Virtual link should be configured on both routers

5.3.7 Neighbors

Submenu level: /routing ospf neighbor

Description

The submenu provides an access to the list of OSPF neighbors, id est the routers adjacent to the current router, and supplies brief statistics

Property Description

address (read-only: IP address) - appropriate IP address of the neighbor

backup-dr-id (read-only: IP address) - backup designated router's router id for this neighbor

db-summaries (read-only: integer) - number of records in link-state database advertised by the neighbor

dr-id (read-only: IP address) - designated router's router id for this neighbor

ls-requests (read-only: integer) - number of link-state requests

ls-retransmits (read-only: integer) - number of link-state retransmits

priority (read-only: integer) - the priority of the neighbor which is used in designated router elections via Hello protocol on this network

router-id (read-only: IP address) - the router-id parameter of the neighbor

state (read-only: Down Attempt Init 2-Way ExStart Exchange Loading Full) - the state of the connection:

Down - the connection is down

Attempt - the router is sending Hello protocol packets

Init - Hello packets are exchanged between routers to create a Neighbor Relationship

2-Way - the routers add each other to their Neighbor database and they become neighbors ExStart - the DR (Designated Router) and BDR (Backup Designated Router) create an adjancency with each other and they begin creating their link-state databases using Database Description Packets Exchange - is the process of discovering routes by exchanging Database Description Packets Loading - receiving information from the neighbor

Full - the link-state databases are completely synchronized. The routers are routing traffic and continue sending each other hello packets to maintain the adjacency and the routing information state-changes (read-only: integer) - number of connection state changes

￿

The neighbor's list also displays the router itself with 2-Way state
