router ID or a configured loopback IP address, the router interface which the packet is received is
ignored.
The LSR path order is optionally specified using the
order
keyword. The
order number
parameter is
an integer value from 1 to 65535. IP prefixes with a lower number are sequenced before IP prefixes with
a higher number. You can specify multiple paths and assign them an order number. The order number
determines the path that the LSP follows. Thus, the LSP path follows the configured path of the IP
prefix with the order value from low to high. If the
order
keyword is not specified, the number value
for the LSR defaults to a value 100 higher than the current highest number value.
If the list of IP prefixes, added to the path, does not reflect an actual path through the network topology,
the path message is returned with an error from a downstream LSR and the LSP is not established.
The order of a configured subobject can not be changed. The ERO subobject must be deleted and
re-added using a different order. If a subobject is added to or deleted from the ERO while the associated
LSP is established, the path is torn down and is signaled again using the new ERO.
Duplicate ERO subobjects are not allowed. Defining an ERO for the path is optional. If you do not
configure an ERO, the path is signaled along the best-routed path and the ERO is not included in the
path message. When the last subobject in the ERO of the path message is reached and the egress IP
node of the path has not been reached, the remaining path to the egress node is signaled along the
best-routed path. Specification of an ERO could lead to undesirable routed paths, so you should be
careful when terminating the ERO routed-path definition prior to the configured path egress node.
Example
The following command adds a strict ERO subobject of 192.18.32.5 to the specified path:
configure mpls rsvp-te path paththroughdenver add ero ipaddress 192.18.32.5
