7.4. RT Redirect (rt-redirect) Sub-Type 0x08

The redirect Extended Community allows the traffic to be redirected to a VRF routing instance that lists the specified route-target in its import policy. If several local instances match this criteria, the choice between them is a local matter (for example, the instance with the lowest Route Distinguisher value can be elected).

This Extended Community allows 3 different encodings formats for the route-target (type 0x80, 0x81, 0x82). It uses the same encoding as the Route Target Extended Community in Sections 3.1 (type 0x80: 2-octet AS, 4-octet value), 3.2 (type 0x81: 4-octet IPv4 address, 2-octet value), and 4 of [RFC4360] and Section 2 of [RFC5668] (type 0x82: 4-octet AS, 2-octet value) with the high-order octet of the Type field 0x80, 0x81, 0x82 respectively and the low-order octet of the Type field (Sub-Type) always 0x08.
