R3303-HP HSR6800 Routers Layer 3 - IP Routing Command Reference

28
mask: Specifies the mask of the IP address, in dotted decimal notation.
mask-length: Specifies the mask length in the range of 0 to 32.
next-hop-address: Specifies IP address of the next hop, in dotted decimal notation.
interface-type interface-number: Specifies the outgoing interface by its type and number. If the outgoing
interface is a nonbroadcast multiaccess (NBMA) interface or broadcast interface (such as an Ethernet
interface, a virtual template interface, or a VLAN interface), rather than a point-to-point (P2P) interface,
the next hop address must be specified.
vpn-instance d-vpn-instance-name: Specifies a destination MPLS L3VPN. d-vpn-instance-name is a
case-sensitive string of 1 to 31 characters. If a destination VPN is specified, the device will search for the
outgoing interface in the destination VPN based on the configured next-hop-address.
next-hop-address public: Indicates that the specified next-hop-address is a public network address, rather
than a VPN instance address.
preference preference-value: Specifies the preference of the static route, which is in the range of 1 to 255.
The default is 60. If no preference is specified, the default preference is used. When the default
preference is re-configured, it applies to newly added static routes only.
tag tag-value: Sets a tag value for the static route from 1 to 4294967295. The default is 0. Tags of routes
are used in routing policies to control routing. For more information about routing policies, see Layer
3—IP Routing Configuration Guide.
permanent: Specifies the route as a permanent static route. If the outgoing interface is down, the
permanent static route is still active.
description description-text: Configures a description for the static route, which consists of 1 to 60
characters, including special characters like space, but excluding the question mark (?).
bfd: Enables the bidirectional forwarding detection (BFD) function to detect reachability of the static
route's next hop. Once the next hop is unreachable, the system will switch to a backup route.
control-packet: Implements BFD in the control packet mode.
echo-packet: Implements BFD in the echo packet mode.
track track-entry-number: Associates the static route with a track entry specified by its number in the
range of 1 to 1024. For more information about track, see High Availability Configuration Guide.
multiple-topology topology-name: Specifies a topology. topology-name is a case-sensitive string of 1 to
31 characters.
Usage guidelines
When you configure a unicast static route, follow these guidelines:
• If the destination IP address and the mask are both 0.0.0.0 (or 0), the configured route is a default
route. The default route is used for forwarding packets that match no specific entry in the routing
table.
• Implement different routing policies by tuning route preference. For example, to enable multiple
routes to the same destination address to share load, assign the same preference to the routes. To
enable them to back up one another, assign different preferences to them.
• Specify the outgoing interface or the next hop address of the static route as needed. The next hop
address cannot be the IP address of a local interface. Otherwise, the route configuration will not
take effect. If the outgoing interface supports network address-to-link layer address resolution or is
a point-to-point interface, you can specify only the interface or the next hop address of the static
route.
