Currently when a static route is created, Netvisor installs a route entry in the routing information database (RIB) regardless of the reachability of the gateway. When static routes are conditional over BFD neighbor-ship formation, Netvisor alleviates this issue.

Netvisor supports static route reachability detection by using BFD protocol, and a static route entry is installed in the RIB only if BFD is able to communicate with the gateway. After installation, BFD periodically monitors reachability and removes the route if connectivity is interrupted. The Pluribus vRouter acts as a gateway, and sends out BFD hellos periodically to specified neighbors. Static BFD sessions are also configurable.

IPv4 and IPv6 addresses are both supported.

Syntax   vrouter-static-bfd-add vrouter-name name-string src-ip ip-address dst-ip ip-address type single-hop|multi-hop


vrouter-name name-string

Specify the vRouter name.

src-ip ip-address

Specify the source IPv4 or IPv6 address.

dst-ip ip-address

Specify the IPv4 or IPv6 destination address.

type single-hop|multi-hop

Specify the type of bi-directional forwarding hop, either single-hop or multi-hop.

Defaults   None

Access   Network Administrator

History   Command introduced in Version 2.5.3.

Usage   Use this command to add BFD to a static route.

Examples  To add BFD to a static route with source IP address, to destination IP address,, use the following syntax:

CLI network-admin@switch > vrouter-static-bfd-add src-ip dst-ip type single-hop
