IP Next Hop Configuration Options
Command Syntax and Usage
[no] set ip dscp <0‐63> [access­list <1‐32>]
Sets the IP DSCP value in the IP header for packets that match route map
policy.
Command mode: Route map
[no] set ip next­hop <IP addresses> [access­list <1‐32>]
Sets the IP addresses for the next‐hop to which packets are forwarded for each
specified access list. When multiple addresses are specified they are
prioritized in the order in which they are entered. Each next‐hop must be an
adjacent router.
Use the no form of the command to remove the entry.
Command mode: Route map
[no] set ip next­hop verify­availability <IP address>
<sequence (1‐255)> [arp|icmp] [interval <1‐60>] [retry <1‐3>]
[access­list <1‐32>]
Performs health‐checking on and inserts the next hop IP address at the
specified place (sequence) in the specified access list using ARP or ICMP as the
tracking protocol. If not successful, the command will retry the health check at
regular intervals of the specified number of seconds for the number of retries
specified by retry. Use the no form of the command to remove the entry.
Default values are arp, 2 seconds, and 3 retries.
Note: This command overrides the "set ip next­hop <IP address>"
command.
