Configures

Snapshot routing

Default

Disabled

Description

Configures a client or a server router for snapshot routing. Snapshot routing is useful for dial-on-demand connections where you don’t want routing updates to bring up the link but you still want to use a dynamic routing protocol (as opposed to static routes). When performing snapshot routing, the router alternates between active periods, when it contacts all the route servers and builds a snapshot route table, and quiet periods, when the snapshot route table is used and no route updates are performed.

active-time

Time in minutes during which routing updates are exchanged between client and server. The value can be from 5 to 100.

quiet-time

Time in minutes for which routing updates are suppressed after an active period.

suppress-statechange-updates

Optional. Disables routing updates during interface state changes.

dialer

Optional. Tells the router that it needs to dial the remote router.

Example

To configure a client for snapshot routing:

interface dialer 1
 snapshot client 2 100 suppress-statechange-updates dialer

To configure a server for snapshot routing:

interface dialer 1
 snapshot server 2
