While protection is enabled globally for all node SIDs and local adjacency SIDs when
the user enables the loopfree-alternates option in IS-IS or OSPF at the LER and
LSR, there are applications where the user wants traffic to never divert from the strict
hop computed by CSPF for an SR-TE LSP. In that case, use the following syntax to
disable protection for all adjacency SIDs formed over a particular network IP
interface:
CLI Syntax: config>router>ospf>area>if>no sid-protection
config>router>isis>if>no sid-protection
Example: node-sid index 194
no sid-protection
no shutdown
3.23.6 Configuring PCC-controlled, PCE-computed, and
PCE-controlled SR-TE LSPs
The following example shows the configuration of PCEP PCC parameters on LER
routers that require peering with the PCE server:
Example: keepalive 30
dead-timer 120
no local-address
unknown-message-rate 10
report-path-constraints
peer 192.0.0.226
no shutdown
exit
no shutdown
The following example shows the configuration of a PCC-controlled SR-TE LSP that
is not reported to the PCE:
Example: lsp "to-SanFrancisco" sr-te
to 192.0.2.211
cspf
pce-report disable
metric 10
primary "loose-anycast"
exit
no shutdown
exit
