Relative Route Priorities - Extreme Networks ExtremeWare XOS Guide Manual

IPv4 Unicast Routing
Dynamic routes
●
Directly attached network interfaces that are not active.
●
NOTE
If you define multiple default routes, the route that has the lowest metric is used. If multiple default routes have the
same lowest metric, the system picks one of the routes.
You can also configure blackhole routes—traffic to these destinations is silently dropped.
The criteria for choosing from multiple routes with the longest matching network mask is set by
choosing the relative route priorities.

Relative Route Priorities

Table 65 lists the relative priorities assigned to routes depending on the learned source of the route.
NOTE
Although these priorities can be changed, do not attempt any manipulation unless you are expertly familiar with the
possible consequences.

To change the relative route priority, use the following command:
configure iproute {ipv4} priority [rip | blackhole | bootp | ebgp | ibgp | icmp |
static | ospf-intra | ospf-inter | ospf-as-external | ospf-extern1 | ospf-extern2]
