Supported match and set conditions
The supported match and set conditions of a normal route-map configuration are as follows:
Match Conditions TABLE 55
Match Conditions
ip nexthop prefix-list prefixList
ip nexthop accessList
interface interfaceName
metric metricValue
tag routeTagValue
protocol-type protocol route type and (or) sub-type value
route-type route type (IS-IS sub-type values)
Set Conditions TABLE 56
Set Conditions:
metric metricValue
metric-type type1/type2
tag routeTagValue
OSPF non-stop routing
The graceful restart feature supported by open shortest path first (OSPF) maintains area topology and
dataflow. Though the network requires neighboring routers to support graceful restart and perform
hitless failover, the graceful restart feature may not be supported by all routers in the network. To
eliminate this dependency, the non-stop routing (NSR) feature is supported on Brocade devices. NSR
does not require support from neighboring routers to perform hitless failover. NSR does not support
virtual link, so traffic loss is expected while performing hitless failover.
NSR does not require support from neighboring
routers to perform hitless failover.
If the active management module fails, the standby management module takes over and maintains the
current OSPF routes, link-state advertisements (LSAs), and neighbor adjacencies, so that there is no
loss of existing traffic to the OSPF destination.
