isis	Specifies IS-IS and applies only to blackhole routes installed for summary addresses.
isis-level-1	Specifies IS-IS Level 1 routing.
isis-level-1-external	Specifies IS-IS Level 1 External routing.
isis-level-2	Specifies IS-IS Level 2 routing.
isis-level-2-external	Specifies IS-IS Level 2 External routing.
mpls	Specifies MPLS (Multiprotocol Label Switching) routing.
ospf-as-external	Specifies OSPF (Open Shortest Path First) as External routing.
ospf-extern1	Specifies OSPF External 1 routing.
ospf-extern2	Specifies OSPF External 2 routing.
ospf-inter	Specifies OSPFInter routing.
ospf-intra	Specifies OSPFIntra routing.
rip	Specifies RIP (Routing Information Protocol).
static	Specifies static routes.
`priority`	Specifies a priority number in the range of 11 to 65534.
`vrname`	Specifies a VR or VRF name.

Usage Guidelines

Although these priorities can be changed, do not attempt any manipulation unless you are expertly familiar with the possible consequences. If you change the route priority, you must save the configuration and reboot the system.
