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-id of 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
