--------------------------------------
Type: Technical
Reported by: Alexander ("Sasha") Vainshtein <[email-masked]>

Section: Section 5

Original Text
-------------
The UMR is characterized as follows:

   o  EVPN Route Type is equal to MAC/IP Advertisement Route

   o  MAC address length is equal to 0

   o  IP address length is equal to 0

Corrected Text
--------------
In Section 5:

The UMR is characterized as follows:

   o  EVPN Route Type is equal to MAC/IP Advertisement Route

   o  MAC address length is equal to 48

   o  IP address length is equal to 0

Notes
-----
The original text provides conflicting definitions of the MAC Address Length in the Unknown MAC Route (UMR).

Since the UMR is a MAC/IP Advertisement Route defined in RFC 7432, and since this RFC states that the MAC Address Length in these routes is 48, the text in Section 5 should be corrected to match RFC 7432 as well as the text in Section 1 of this RFC (where MAC Address Length in the UMR is correctly defined as 48).
