Description This command configures the SRLG membership of an interface. The user can apply SRLGs to an
IES, VPRN, network IP, or MPLS interface.
An interface can belong to up to 64 SRLG groups. However, each single operation of the srlg-group
command allows a maximum of five (5) groups to be specified at a time. Once an SRLG group is
bound to one or more interface, its value cannot be changed until all bindings are removed.
The configured SRLG membership will be applied in all levels/areas the interface is participating in.
The same interface cannot have different memberships in different levels/areas.
It should be noted that only the SRLGs bound to an MPLS interface are advertised area-wide in TE
link TLVs and sub-TLVs when the traffic-engineering option is enabled in IS-IS or OSPF. IES and
VPRN interfaces do not have their attributes advertised in TE TLVs.
The no form of this command deletes one or more of the SRLG memberships of an interface. The
user can also delete all memberships of an interface by not specifying a group name.
Parameters group-name — Specifies the name of the group, up to 32 characters. The association of group name

template
Syntax [no] template template-name
Context config>router>route-next-hop-policy
Description
This command creates a template to configure the attributes of a Loop-Free Alternate (LFA) Shortest
Path First (SPF) policy. An LFA SPF policy allows the user to apply specific criteria, such as admin
group and SRLG constraints, to the selection of an LFA backup next-hop for a subset of prefixes that
resolve to a specific primary next-hop.
The user first creates a route next-hop policy template under the global router context and then
applies it to a specific OSPF or IS-IS interface in the global routing instance or in a VPRN instance.
A policy template can be used in both IS-IS and OSPF to apply the specific criteria to prefixes
protected by LFA. Each instance of IS-IS or OSPF can apply the same policy template to one or more
interface.
