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
