Router Global Commands
Page 122 7750 SR OS Router Configuration Guide
Context config>router
Description This command triggers route policy re-evaluation.
By default, when a change is made to a policy in the config router policy options context and then
committed, the change is effective immediately. There may be circumstances when the changes
should or must be delayed; for example, if a policy change is implemented that would affect every
BGP peer on a router, the consequences could be dramatic. It would be more effective to control
changes on a peer-by-peer basis.
If the triggered-policy command is enabled, and a given peer is established, and you want the peer to
remain up, in order for a change to a route policy to take effect, a clear command with the soft or soft
inbound option must be used; for example, clear router bgp neighbor x.x.x.x soft . This keeps the
peer up, and the change made to a route policy is applied only to that peer or group of peers.
single-sfm-overload
Syntax single-sfm-overload [ holdoff-time holdoff-time ]
no single-sfm-overload
Context config>router
Description This command, if enabled, will cause the OSPF for the service to enter an overload state when the
node has fewer than the full set of SFMs functioning. Once a significant amount of multicast capacity
is lost due to missing SFM(s) then the overload state will be entered.
The no form of this command causes the overload state to be cleared.
Default
no single-sfm-overload
Parameters
holdoff-time — This parameter specifies the delay between the detection of a single SFM and
enacting the overload state.
Values
1— 600 seconds
Default
0 seconds
