Relationships between routing protocol values and priorities on the USG6000 series

3

In routing protocols, 0 indicates the direct route, and 255 indicates any route learned from unreliable sources. A smaller value indicates a higher priority.

In routing protocols, 0 indicates the direct route, and 255 indicates any route learned from unreliable sources. A smaller value indicates a higher priority.

Relationship between the actual setup and holding priorities of CR-LSP tunnels and the priority values
CR-LSP tunnels use the setup priority and holding priority to determine whether to preempt resources. The priority value ranges from 0 to 7. A smaller value allows for a higher priority. The setup priority must be lower than or equal to the holding priority for a tunnel. The priority and the preemption attributes are used together to determine resource preemption among tunnels. If multiple CR-LSP tunnels are to be established, CR-LSP tunnels with higher priorities can be established by preempting resources. When the bandwidth is insufficient, resources of an established LSP tunnel with a lower holding priority may be preempted by an LSP tunnel with a higher setup priority.

Priorities of policy-based routing and default routing for an AR router
Policy-based routing has a higher priority than default routing. If policy-based routing and default routing coexist, only policy-based routing takes effect. After policy-based routing loses effect, default routing takes effect.

Modifying the routing protocol priority on the firewall
The method for modifying the routing protocol priority on the USG2000&5000&6000 is as follows: -Modifying the static routing protocol priority: [USG]ip route-static 192.168.0.0 16 10.1.1.1 preference 20 -Modifying the RIP priority: [USG]rip [USG-rip-1]preference 80 -Modifying the OSPF priority: [USG]ospf [USG-ospf-1]preference 30 -Modifying the IS-IS priority: [USG]isis [USG-isis-1]preference 90 -Modifying the BGP priority: [USG]bgp 25212 [USG-bgp]ipv4-family unicast [USG-bgp-af-ipv4]preference 120
