Known Affected Releases
Release-note Symptom: BGP ipv4 mvpn global table type 7 route disappear on tail node and multicast traffic drop. Conditions: This issue occurs under the following scenario: 1. Global-table-multicast is enabled under router bgp address-family ipv4 mvpn 2. There is no vrf configured under router bgp. 3. Route-reflector-client is configured under ipv4 mvpn for some neighbor. If the above conditions are met, when bgp session flaps (ipv4 mvpn type 1 route flaps), bgp will no longer install remote received type 1 route in PIM which will result in type 7 not getting regenerated. This is the PE/RR case for global-table-multicast.
