Description This command configures the delay period the SDP must wait before it reverts to a higher priority
LSP type when one becomes available.
The no option resets the timer to the default value of 0. This means the SDP reverts immediately to a
higher priority LSP type when one becomes available.
Default 0
Parameters seconds — Specifies the delay period, in seconds, that the SDP must wait before it reverts to a higher
priority LSP type when one becomes available. A value of zero means the SDP reverts
immediately to a higher priority LSP type when one becomes available.
Values 0 — 600 seconds
infinite — This keyword forces the SDP to never revert to another higher priority LSP type unless the
currently active LSP type is down..
signaling
Syntax signaling {off | tldp | bgp}
Context config>service>sdp
Description This command specifies the signaling protocol used to obtain the ingress and egress pseudowire
labels in frames transmitted and received on the SDP. When signaling is off then labels are manually
configured when the SDP is bound to a service. The signalling value can only be changed while the
administrative status of the SDP is down. Additionally, the signaling can only be changed on an SDP
if that SDP is not in use by BGP-AD or BGP-VPLS. BGP signaling can only be enabled if that SDP
does not already have pseudowires signaled over it. Also, BGP signaling is not supported with mixed
mode LSP SDPs.
The no form of this command is not applicable. To modify the signaling configuration, the SDP must
be administratively shut down and then the signaling parameter can be modified and re-enabled.
Default tldp
Parameters off — Ingress and egress signal auto-labeling is not enabled. If this parameter is selected, then each
service using the specified SDP must manually configure VPN labels. This configuration is
independent of the SDP’s transport type, GRE, MPLS (RSVP or LDP).
tldp — Ingress and egress pseudowire signaling using T-LDP is enabled. Default value used when
BGP AD automatically instantiates the SDP.
bgp — Ingress and egress pseudowire signaling using BGP is enabled. Default value used when BGP
VPLS automatically instantiates the SDP.
