Interfaces in this case). It allows you to backup Indirect Next-hop with another, choose the specic Indirect Next-hop and/or Tunnel
Interface which is available by sending ICMP pings to verify reach ability and/or check the Tunnel Interface UP or DOWN status, and then
route trac out to that next-hop and/or Tunnel Interface

Non-contiguous bitmasks for PBR
Non-contiguous bitmasks for PBR allows more granular and exible control over routing policies. Network addresses that are in the middle
of a subnet can be included or excluded. Specic bitmasks can be entered using the dotted decimal format.
Non-contiguous bitmask example
Dell#show ip redirect-list
IP redirect-list rcl0:
Defined as:
seq 5 permit ip
200.200.200.200 200.200.200.200 199.199.199.199 199.199.199.199
seq 10 redirect 1.1.1.2 tcp 234.224.234.234 255.234.234.234
222.222.222.222/24
seq 40 ack, Next-hop reachable(via Te 8/1/1)
Applied interfaces:
Te 8/2/1
Hot-Lock PBR
Hot Lock PBR allow you to add or delete new rules into an existing policy (already written into CAM) without disruption to trac ow.
Existing entries in CAM are adjusted to accommodate the new entries. Hot Lock PBR is enabled by default.
Conguration Task List for Policy-based Routing
To enable the PBR:
• Create a Redirect List
• Create a Rule for a Redirect-list
• Create a Track-id list. For complete tracking information, refer to Object Tracking chapter.
• Apply a Redirect-list to an Interface using a Redirect-group
Create a Redirect List
Use the following command in CONFIGURATION mode:
Table 68. Create a Redirect List
Command Syntax Command Mode Purpose
ip redirect-list redirect-list-name CONFIGURATION Create a redirect list by entering the list
name.
Format: 16 characters
Delete the redirect list with the no ip redirect-list command.
