The user can select if link protection or node protection is preferred in the selection of a LFA next-hop for all IP prefixes and LDP FEC prefixes to which a route next-hop policy template is applied. The default in SR OS implementation is node protection. The implementation falls back to the other type if no LFA next-hop of the preferred type is found.
The user can also select if IP backup next-hop. The default in SR OS implementation is to prefer IP next-hop as only IP backup next hop is supported on the 7210 SAS.
The following options are therefore added into the Route next-hop policy template:
configure router route-nh-template template template-name
protection-type {link | node}
nh-type {ip}
When the route next-hop policy template is applied to an IP interface, all prefixes using this interface as a primary next-hop follow the protection type and next-hop type preference specified in the template.
