authentication algorithm

This command defines authentication algorithm.

The use of a negative form (no) of the command disables the authentication.

Syntax

no authentication algorithm

Parameters

<ALGORITHM> – authentication algorithm:

• cleartext – password, transmitted in unencrypted form (available only for RIP and OSPF-VLINK);
• md5 – password is hashed by md5 algorithm.

authentication key

This command sets a password for authentication with a neighbor.

The use of a negative form (no) of the command removes the password.

IPv4/IPv6 static routes configuration

ip route

This command creates a static IP route to the specified subnet.

The use of a negative form (no) of the command removes a specified route.

Syntax

ip route [ vrf <VRF> ] <SUBNET> { <NEXTHOP> [ resolve ] | interface <IF> | tunnel <TUN> | wan load-balance rule <RULE> | blackhole | unreachable | prohibit } [ <METRIC> ] [ track <TRACK-ID> ] [ bfd ] [ name <NAME>]

no ip route [ vrf <VRF> ] <SUBNET> [ <METRIC> ]

Parameters

<VRF> – VRF name, set by the string of up to 31 characters.

<SUBNET> – destination address, can be specified in the following formats:

• AAA.BBB.CCC.DDD – host IP address, where each part takes values of [0..255].
• AAA.BBB.CCC.DDD/NN – network IP address with prefix mask, where AAA-DDD take values of [0..255] and NN takes values of [1..32].

<NEXTHOP> – gateway IP address, defined as AAA.BBB.CCC.DDD where each part takes values of [0..255].

resolve – when specifying this parameter, gateway IP address will be recursively calculated through the routing table. If the recursive calculation fails to find a gateway from a directly connected subnet, then this route will not be installed into the system.

<IF> – an IP interface name specified in the form described in Section Types and naming order of router interfaces.

<TUN> – the name of the tunnel is specified as described in section Types and naming order of router tunnels.

<RULE> – wan rule number, set in the range of [1..50].

blackhole – when specifying the command, the packets to this subnet will be removed by the device without sending notifications to a sender;

unreachable – when specifying the command, the packets to this subnet will be removed by the device, a sender will receive in response ICMP Destination unreachable (Host unreachable, code 1);

prohibit – when specifying the command, the packets to this subnet will be removed by the device, a sender will receive in response ICMP Destination unreachable (Communication administratively prohibited, code 13);

<METRIC> – route metric, takes values of [0..255].

<TRACK-ID> – Tracking object identifier. If the router is bound to the Tracking object, it will appear in the system only after meeting all requirements specified in the object.

<NAME> – name (description) of the route, text variable up to 31 characters long.

bfd – when specifying this key, the removal of static route in case of next-hop unavailability is activated. For operation of this mechanism, the BFD mechanism must be running with the IP address of the next-hop (see section ip bfd neighbor).

next-hop check using bfd protocol. If next-hop is unavailable, the route is deleted.

key-chain ipv6 route

This command creates a static IPv6 route to the specified subnet.

The use of a negative form (no) of the command removes a specified route.

Syntax

ipv6 route [ vrf <VRF> ] <SUBNET> { <NEXTHOP> [ resolve ] | interface <IF> | wan load-balance rule <RULE> | blackhole | unreachable | prohibit } [ <METRIC> ] [bfd] [ name <NAME>]

no ipv6 route [ vrf <VRF> ] <SUBNET> [ <METRIC> ]

Parameters

<VRF> – VRF name, set by the string of up to 31 characters.

<SUBNET> – destination address, can be specified in the following formats:

• The addresses are defined as X:X:X:X::X where each part takes values in hexadecimal format [0..FFFF].
• <IPV6-ADDR/LEN> – IP address and mask of a subnet, defined as X:X:X:X::X/EE where each X part takes values in hexadecimal format [0..FFFF] and EE takes values of [1..128].

<IPV6-ADDR> – client IPv6 address, defined as X:X:X:X::X where each part takes values in hexadecimal format [0..FFFF].

resolve – when specifying this parameter, gateway IPv6 address will be recursively calculated through the routing table. If the recursive calculation fails to find a gateway from a directly connected subnet, then this route will not be installed into the system.

<IF> – an IP interface name specified in the form described in Section Types and naming order of router interfaces.

blackhole – when specifying the command, the packets to this subnet will be removed by the device without sending notifications to a sender.

unreachable – when specifying the command, the packets to this subnet will be removed by the device, a sender will receive in response ICMP Destination unreachable (Host unreachable, code 1).

prohibit – when specifying the command, the packets to this subnet will be removed by the device, a sender will receive in response ICMP Destination unreachable (Communication administratively prohibited, code 13).

<METRIC>  – route metric, takes values of [0..255].

<NAME> – name (description) of the route, text variable up to 31 characters long.

bfd - when specifying this key, the next-hop check is activated using the bfd protocol. If next-hop is unavailable, the route is deleted.

ipv6 ospf neighbor

This command statically sets the IPv6 address of the neighbor to establish a relationship in NMBA and P2MP (Point-to-MultiPoint) networks. The use of a negative form (no) of the command removes a statically specified neighbor address.

Syntax

[no] ipv6 ospf neighbor <IPV6-ADDR> [ eligible ]

Parameters

<IPV6-ADDR> – neighbor’s IPv6 address, defined as X:X:X:X::X where each part takes values in hexadecimal format [0..FFFF];

eligible – optional parameter, allows the device to take part in DR selection process in NMBA networks. The priority of the interface must be greater than zero, the command for changing the priority is described in section ip ospf priority.
