VPRN Service Configuration Commands
Page 970 7750 SR OS Services Guide
to determine the static route to install in the forwarding table: When modifying the metrices of an
existing static route, unless specified, the preference will not change.
If there are multiple static routes with the same preference but unequal metrices, the lower cost
(metric) route is installed. If there are multiple static routes with equal preference and metrics
then ECMP rules apply. If there are multiple routes with unequal preferences, then the lower
preference route is installed.
Default 1
Values 0 — 65535
tag — Adds a 32-bit integer tag to the static route. The tag is used in route policies to control
distribution of the route into other protocols.
bfd-enable — Associates the state of the static route to a BFD session between the local system and
the configured nexthop. This keyword cannot be configured if the nexthop is indirect or a
blackhole keywords are specified.
