Abstract Abstract
Bit Index Explicit Replication (BIER) can be used as provider tunnel Bit Index Explicit Replication (BIER) can be used as provider tunnel
for MVPN/GTM [RFC6514] [RFC7716] or EVPN BUM [RFC7432]. It is for MVPN/GTM [RFC6514] [RFC7716] or EVPN BUM [RFC7432]. It is
possible that not all routers in the provider network support BIER possible that not all routers in the provider network support BIER
and there are various methods to handle BIER incapable transit and there are various methods to handle BIER incapable transit
