Please compare the BESS L3VPN Yang data model with the base BGP model handling of AFI/SAFI. Sue From: BESS [mailto:[email protected]] On Behalf Of Qin Wu Sent: Thursday, July 25, 2019 2:23 PM To: [email protected]; [email protected] Subject: [bess] per VRF RD vs per address family RD Hi, Folks: RFC4659 said: " When a site is IPv4 capable and IPv6 capable, the same RD MAY be used for the advertisement of IPv6 addresses and IPv4 addresses. Alternatively, a different RD MAY be used for the advertisement of the IPv4 addresses and of the IPv6 addresses. " But in BESS L3VPN YANG data model, onely same RD for the advertisement of IPv6 address and IPv4 address is supported, see the following model structure snippet: augment /ni:network-instances/ni:network-instance/ni:ni-type: +--:(l3vpn) +--rw l3vpn +--rw rd? bgp-rd-type +--ro auto-rd? rt-types:route-distinguisher +--rw ipv4 | +--rw unicast | +--rw vpn-targets I am wondering why per address family RD is not supported ,i..e, different RD for advertisment of the IPv4 addresses and of the IPv6 address. If this is something that have been discussed, please point me the link , thanks for clarification. -Qin
