interface user needs to provide tunnel id mandatory. Instead if user provides the tunnel destination IP as next

hop, that would be treated as IPv4 next hop and not tunnel next hop.

PBR with Multiple Tacking Option:

Policy based routing with multiple tracking option extends and introduces the capabilities of object tracking

to verify the next hop IP address before forwarding the traffic to the next hop. The verification method is

made transparent to the user. The multiple tracking options feature is most suitable for routers which have

multiple devices as the next hop (primarily indirect next-hops and/or Tunnel Interfaces in this case). It allows

you to backup Indirect Next-hop with another, choose the specific 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 traffic out to that next-hop and/or Tunnel Interface

Non-contiguous bitmasks for PBR

Non-contiguous bitmasks for PBR allows more granular and flexible control over routing policies. Network

addresses that are in the middle of a subnet can be included or excluded. Specific bitmasks can be entered

using the dotted decimal format.

Non-contiguous bitmask example

Dell#show ip redirect-list

IP redirect-list rcl0:

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:

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 traffic flow. Existing entries in CAM are adjusted to accommodate the new entries. Hot Lock PBR

is enabled by default.
