add hop

Function

The add hop command adds a specified node to an MPLS TE explicit path.

By default, no node is add to an explicit path.

Format

add hop ip-address1 [ exclude | include [ [ strict | loose ] | [ incoming | outgoing ] ] ^* ] { after | before } ip-address2

add hop ip-address1 [ exclude | include [ [ strict | loose ] | [ incoming | outgoing ] ] ^* ] { after | before } { hop ip-address2 | index indexValue | sid label contrastLabel index indexValue }

Parameters

Parameter	Description	Value
ip-address1	Specifies an IPv4 address. If the strict mode is configured for the next hop, specify an interface address.	The value is in dotted decimal notation.
exclude	Excludes the ip-address1 node from an explicit path.	-
include	Includes the ip-address1 node on an explicit path.	-
strict	Indicates the strict explicit path. The added ip-address1 node and the ip-address2 node must be directly connected.	-
loose	Indicates the loose explicit path. The ip-address1 node and the ip-address2 node can be directly or indirectly connected.	-
incoming	Indicates the inbound interface.	-
outgoing	Indicates the outbound interface.	-
after	Adds the ip-address1 node after the node ip-address2 node.	-
before	Adds the ip-address1 node before the ip-address2 node.	-
ip-address2	Hop ip address.	The value is in dotted decimal notation.
index indexValue	Index value.	The value is an integer ranging from 1 to 96.
sid	SID value.	-
label contrastLabel	Label value.	The value is an integer ranging from 16 to 1048575.

Usage Guidelines

Usage Scenario

The command takes effect only if the node resides on the explicit path, and no interface on the node is using this explicit path.

Example

# Add the next hop of 10.3.29.3 after the node of 10.3.10.5 on the explicit path named p1.

<HUAWEI> system-view
[~HUAWEI] mpls
[*HUAWEI-mpls] mpls te
[*HUAWEI-mpls] quit

[*HUAWEI-explicit-path-p1] next hop 10.3.10.5
[*HUAWEI-explicit-path-p1] add hop 10.3.29.3 include after 10.3.10.5
