Example for Configuring the Affinity Attribute of an MPLS TE Tunnel
Networking Requirements
On the network shown in Figure 1, the bandwidth of the link between LSRA and LSRB is 50 Mbit/s. The maximum reservable bandwidth of other links is 100 Mbit/s, and BC0 bandwidth is 100 Mbit/s.
Two tunnels named Tunnel1 and Tunnel2 from LSRA to LSRC are established on LSRA. Both tunnels require 40 Mbit/s of bandwidth. The combined bandwidth of these two tunnels is 80 Mbit/s, higher than the bandwidth of 50 Mbit/s provided by the shared link between LSRA and LSRB. In addition, Tunnel2 has a higher priority than Tunnel1, and preemption is enabled.
In this example, SRLG attributes, affinities, and masks for links are used to allow Tunnel1 and Tunnel2 on LSRA to use separate links between LSRB and LSRC.
Configuration Roadmap
The configuration roadmap is as follows:
Configure an RSVP-TE tunnel. See "Configuration Roadmap" in Example for Configuring an RSVP-TE Tunnel.
Configure an SRLG attribute on an outbound interface of every LSR along each RSVP TE tunnel.
Configure the affinity and mask for each tunnel based on the administrative groups of links and networking requirements.
Set a priority value for each tunnel.
Data Preparation
To complete the configuration, you need the following data:
OSPF process ID and area ID for every LSR
Maximum reservable bandwidth and BC bandwidth for every link along each tunnel
Administrative groups for links between LSRA and LSRB and between LSRB and LSRC
Affinity and mask for each tunnel
Tunnel interface number, source and destination IP addresses, bandwidth, priority values, and RSVP-TE signaling protocol of the tunnel
Procedure
- Assign an IP address and its mask to every interface.
Assign an IP address and its mask to every physical interface and configure a loopback interface address as an LSR ID on every node according to Figure 1.
For configuration details, see Configuration Files in this section.
- Configure an IGP.
Configure OSPF on every LSR to advertise every network segment route and host route.
For configuration details, see Configuration Files in this section.
- Configure basic MPLS functions, enable MPLS TE, RSVP-TE, and OSPF TE on every LSR, and enable CSPF on the ingress.
# Configure basic MPLS functions and enable MPLS TE and RSVP-TE on every LSR.

The default setup and hold priorities (lowest: 7) are used.
The mask of Tunnel1's affinity attribute is 0x11011. As such, the first two bits of the affinity attribute value need to be compared, so do the last two bits. In contrast, the third bit in the middle is ignored. Because the affinity value of Tunnel1 is 0x10101, this tunnel selects the link with the second and fourth bits of the administrative group attribute being 0 and at least one of the first and fifth bits being 1. According to the preceding rules, if the value of the administrative group attribute is 0x10001, 0x10000, 0x00001, 0x10101, 0x10100, or 0x00101, the value meets requirements. Tunnel1 then selects the link between GE 0/1/0 of LSRA (the administrative group value is 0x10001) and GE 0/1/8 of LSRB (the administrative group value is 0x10101).
After completing the configuration, run the display mpls te tunnel-interface command on LSRA. The tunnel status is displayed.

[7] indicates that bandwidth of 40 Mbit/s has been successfully reserved for a tunnel. The bandwidth information also matches the path of a tunnel. This proves that the affinity and mask match the administrative group of every link.
Alternatively, run the display mpls te tunnel diagnostic command to check the outbound interfaces of links along the tunnel on LSRB.

The mask of Tunnel2's affinity attribute is 0x11101. As such, the first three bits of the affinity attribute value need to be compared, so do the last bit. In contrast, the fourth bit is ignored. Because the affinity value of Tunnel2 is 0x10011, this tunnel selects the link with the second and third bits of the administrative group attribute being 0 and at least one of the first and fifth bits being 1. According to the preceding rules, if the value of the administrative group attribute is 0x10001, 0x10000, 0x00001, 0x10011, 0x10010, or 0x00011, the value meets requirements. Tunnel2 then selects the link between GE 0/1/0 of LSRA (the administrative group value is 0x10001) and GE 0/1/16 of LSRB (the administrative group value is 0x10011).
- Verify the configuration.
After completing the configurations, run the display interface tunnel or display mpls te tunnel diagnostic command on LSRA. The status of Tunnel1 is Down. This is because since the maximum reservable bandwidth is insufficient, Tunnel2 is of a higher priority and has preempted the bandwidth reserved for Tunnel1.
Run the display mpls te cspf tedb node command. TEDB information contains the bandwidth for every link, which indicates that Tunnel2 indeed passes through GE 0/1/16 of LSRB.
Alternatively, run the display mpls te tunnel diagnostic command to check outbound interfaces of links along the tunnel on LSRB.
