Configuration examples

This section presents configuration examples for:

• “Basic example” on page 336

• “Setting the next hop” on page 336

• “Setting the output interface to the null interface” on page 338

• “Selectively applying normal routing to packets” on page 338

Basic example

The following commands configure and apply a PBR policy that routes HTTP traffic received on

virtual routing interface 1 from the 10.10.10.x/24 network to 10.5.5.x/24 through next-hop IP

address 10.1.1.1 or, if 10.1.1.x is unavailable, through 10.2.2.1.

Setting the next hop

The following commands configure the Brocade device to apply PBR to traffic from IP subnets

10.157.23.x, 10.157.24.x, and 10.157.25.x. In this example, route maps specify the next-hop

gateway for packets from each of these subnets:

• Packets from 10.157.23.x are sent to 192.168.2.1.

• Packets from 10.157.24.x are sent to 192.168.2.2.

• Packets from 10.157.25.x are sent to 192.168.2.3.

The following commands configure three standard ACLs. Each ACL contains one of the ACLs listed

above. Make sure you specify permit instead of deny in the ACLs, so that the Brocade device

permits the traffic that matches the ACLs to be further evaluated by the route map. If you specify

deny, the traffic that matches the deny statements are routed normally. Notice that these ACLs

specify any for the destination address.

Brocade(config)# access-list 50 permit 10.157.23.0 10.0.0.255

Brocade(config)# access-list 51 permit 10.157.24.0 10.0.0.255

Brocade(config)# access-list 52 permit 10.157.25.0 10.0.0.255

The following commands set an RSVP-signalled LSP as the next hop.

Brocade(config)# access-list 101 permit tcp any any

Brocade(config)# access-list 101 deny ip any any

Brocade(config)# router mpls

Brocade(config-mpls)# mpls-interface ethernet 6/1

Brocade(config-mpls)# lsp t3

Brocade(config)# access-list 101 permit tcp 10.10.10.0 10.0.0.255 eq http

10.5.5.0 10.0.0.255

Brocade(config)# route-map net10web permit 101

Brocade(config-routemap net10web)# match ip address 101

Brocade(config-routemap net10web)# set ip next-hop 10.1.1.1

Brocade(config-routemap net10web)# set ip next-hop 10.2.2.1

Brocade(config-routemap net10web)# exit

Brocade(config)# vlan 10

Brocade(config-vlan-10)# tagged ethernet 1/1 to 1/4

Brocade(config-vlan-10)# router-interface ve 1

Brocade(config)# interface ve 1
