To ensure that packets destined to host 26.1.1.1 and subnet 26.1.1.0 are sent into the sub-pool tunnel, we create a static route. At the device level:

router-1(config)# ip route 26.1.1.0 255.255.255.0 Tunnel1

And in order to make sure that the Interior Gateway Protocol (IGP) will not send any other traffic down this tunnel, we disable autoroute announce:

router-1(config)# no tunnel mpls traffic-eng autoroute announce

1.    In global configuration mode, create a class of traffic matching ACL 100, called "sla-1-class":

2.    Create an ACL 100 to refer to all packets destined to 26.1.1.1:

3.    Create a policy named "sla-1-input-policy", and according to that policy:

router-1(config-if)# tunnel mpls traffic-eng path-option 1 explicit name gbs-path1
router-1(config-if)# exit

and at a second tunnel interface, create a global pool tunnel:

router-1(config)# interface Tunnel2
router-1(config-if)# ip unnumbered Loopback0
router-1(config-if)# tunnel destination 27.1.1.1
router-1(config-if)# tunnel mode mpls traffic-eng

router-1(config-if)# tunnel mpls traffic-eng path-option 1 explicit name \ best-effort-path1
router-1(config-if)# exit

In this example explicit paths are used instead of dynamic, to ensure that best-effort traffic and guaranteed bandwidth traffic will travel along different paths.

At the device level:

router-1(config)# ip explicit-path name gbs-path1
router-1(config-ip-expl-path)# next-address 24.1.1.1
router-1(config-ip-expl-path)# next-address 27.1.1.1

router-1(config-ip-expl-path)# next-address 27.1.1.1
router-1(config-ip-expl-path)# exit

Note that autoroute is not used, as that could cause the Interior Gateway Protocol (IGP) to send other traffic down these tunnels.

At the inbound network interface (in Figure 8 and Figure 9 this is FE4/0), packets received are rate-limited to:

• a rate of 30 Mbps
• a normal burst of 1 MB
• a maximum burst of 2 MB

Packets that are mapped to qos-group 6 and that conform to the rate-limit are marked with experimental value 5 and the BGP destination community string, and are forwarded; packets that do not conform (exceed action) are dropped:

router-1(config)# interface FastEthernet4/0
router-1(config-if)# rate-limit input qos-group 6 30000000 1000000 2000000 \
 conform-action set-mpls-exp-transmit 5 exceed-action drop
router-1(config-if)# bgp-policy destination ip-qos-map
router-1(config-if)# exit

At the device level create a class of traffic called "exp5-class" that has MPLS experimental bit set to 5:

router-1(config)# class-map match-all exp5-class
router-1(config-cmap)# match mpls experimental 5
router-1(config-cmap)# exit

Create a policy that creates a priority queue for "exp5-class":

router-1(config)# policy-map core-out-policy
router-1(config-pmap)# class exp5-class
router-1(config-pmap-c)# priority 100000
router-1(config-pmap-c)# exit
router-1(config-pmap)# class class-default
router-1(config-pmap-c)# bandwidth 55000
router-1(config-pmap-c)# exit
router-1(config-pmap)# exit

The policy is applied to packets exiting subinterface ATM2/0.4 (first example) or interface POS4/0 (second example)?:

interface atm2/0

service-policy output core-out-policy

interface POS4/0

router-1(config-router)# exit

Create a distinct route map for this service. This includes setting the next-hop of packets matching 29.1.1.1 (a virtual loopback configured in the tail router; see page 57) so they will be mapped onto Tunnel #1 (the guaranteed bandwidth service tunnel). At the device level:

router-1(config-route-map)# exit
router-1(config)# ip as-path access-list 101 permit _5_

Map all guaranteed bandwidth traffic onto Tunnel #1:

router-1(config)# ip route 29.1.1.1 255.255.255.255 Tunnel1

Map all best-effort traffic (traveling toward another virtual loopback interface, 30.1.1.1, configured in the tail router) onto Tunnel #2:

On the tail device, one must configure a separate virtual loopback IP address for each class-of-service terminating here. The headend routers need these addresses to map traffic into the proper tunnels. In the current example, four tunnels terminate on the same tail device but they represent only two service classes, so only two additional loopback addresses are needed:

Create two virtual interfaces:

router-4(config)# interface Loopback1
router-4(config-if)# ip address 29.1.1.1 255.255.255.255
[and if using IS-IS instead of OSPF]:

router-4(config)# interface Loopback2

[and if using IS-IS instead of OSPF]:
router-4(config-if)# ip router isis
[and in all cases]:
router-4(config-if)# exit

At the device level, configure BGP to send the community to each tunnel head:

router-4(config)# router bgp 2
router-4(config-router)# neighbor 23.1.1.1 send-community
router-4(config-router)# neighbor 22.1.1.1 send-community
router-4(config-router)# exit
