Route Distinguisher (RD) Allocation Independent of Route Target (RT)

Provisioning in EFA 2.5.5 or above

The following example shows the allocation of route distinguisher:

Note

• XCO auto allocates VRF RT in the format xx:yy and VRF RD in the format <router-id>:<unique-number-per-vrf-independent-of-rt>.
• RD value has no relation to yy value of RT. XCO auto allocates an unique number of RD for each VRF which is appended to the router ID.
