VINES Overview
117372-A Rev. A 1-13
Every node on a VINES network periodically broadcasts nonsequenced
routing update packets. Nodes on LAN and high-speed media send out
nonsequenced routing update packets every 90 seconds. These packets inform
neighbors of the node’s existence and type. Routes remain in a neighbor’s
routing table for 6 minutes. If the neighbor does not hear from the node again
within 6 minutes, the neighbor marks the route as unreachable and removes it
from the routing table. The packets sent out by service nodes also include a
list of all networks known to the service node and the cost of reaching these
networks from that service node.
On server-to-server connectivity and over WAN connections (TCP/IP, X.25,
HDLC, Block Asynchronous), service nodes send out five full, nonsequenced
routing update packets when the node first comes up on the network.
Afterwards, nonsequenced routing update packets are generated only when
you make routing changes to the network. All routes permanently remain in a
node’s routing table for these types of connections.
Nonsequenced routing request packets
A client node generates nonsequenced routing request packets when it needs
information about the network topology.
Nonsequenced routing response packets
In response to receiving a nonsequenced routing request packet, service nodes
generate nonsequenced routing response packets that describe the network
topology.
Nonsequenced routing redirect packets
A service node generates nonsequenced routing redirect packets when it
determines that a better path exists for forwarding packets between nodes.
The service node sends a nonsequenced routing redirect packet to the last hop
that forwarded the packet, informing it of the existence of a better route. The
service node also sends the original packet toward the destination.
