BFD for multihop path for BGP 7.0.6

In BFD, a FortiGate can support neighbors connected over multiple hops. When BFD is down, BGP sessions are reset and will try to immediately re-establish neighbor connections. Previously, BFD was only supported when two routers or FortiGates were directly connected on the same network.

config router {bfd | bfd6}
    config multihop-template
        edit <ID>
            set src <class_IP/netmask>
            set dst <class_IP/netmask>
            set bfd-desired-min-tx <integer>
            set bfd-required-min-rx <integer>
            set bfd-detect-mult <integer>
            set auth-mode {none | md5}
            set md5-key <password>
        next
    end
end

src <class_IP/netmask>

Enter the source prefix.

dst <class_IP/netmask>

Enter the destination prefix.

bfd-desired-min-tx <integer>

Set the BFD desired minimal transmit interval, in milliseconds (100 - 30000, default = 250).

bfd-required-min-rx <integer>

Set the BFD required minimal transmit interval, in milliseconds (100 - 30000, default = 250).

bfd-detect-mult <integer>

Set the BFD detection multiplier (3 - 50, default = 3).

auth-mode {none | md5}

Set the authentication mode (none or meticulous MD5).

md5-key <password>

Enter the password.
