MPLS TE Attribute Flag
Introduction
Attribute flag is an implementation of coloring. TE links have different custom colors used to describe paths for TE custom policies.
Attribute Flags
- Attribute flags can define 32 different properties of a link.
- Example of these could be a property for a burstable circuit, satellite links, low-latency links, domestic links…etc (see table for these arbitrary values).
Name | Attribute-flag Hex | Attribute-flag Binary |
---|---|---|
Burstable | 0x1 | …0001 |
Satelite | 0x2 | …0010 |
Low-latency | 0x4 | …0100 |
Domestic | 0x8 | …1000 |
- Tunnels can have affinity mask configured to define which flags have to match for a path to be eligible for a particular tunnel.
- To configure a tunnel to only select circuit that are low-latency and domestic:
