hi,
first of all, thanks for reaching out... :)
so srv6 features are almost full along all the dataplanes... for the specific 
use cases, there is a feature support matrix at
rare.freertr.org... long story short, as far as i can remember, layer2 and 
layer3 vpns are all supported over the srv6 core...
but please keep in mind that the software dataplanes like the dpdk and pcap 
based p4emu ones, can do 1/10 if you run the same
over mpls... the reason here is that a patricia tree walk seems more 
expensive compared to a quick-find in an ordered label table...
in case of hardware dataplanes, these are not expressed in tume but in 
consumed power per packet to use the tcam vs the sram...
regarding ovpn, olab and friends, freerouter decided to fully go v4/v6 
agonist, so you have the session address family, which
is declared by bgp4/bgp6 once the process created.... this is the peer 
address family you can peer to, so bgp4 will peer to ipv4
neighbors... then you have the carried address family, which is the customer 
address family provided, and it's a convention here
that we shorted the other as "o"... so ovpnuni over a bgp4 peering is the 
cisco version of vpnv6... but we're more than happy to
bring up vpnuni over an ipv6 peering, in this case it's the same ipv6 
customer routes, but over an ipv6 (srv6) core...
one more thing to note, freerotuer's bgp implementation acts as a bgp 
attribute firewall, by default... if you want to send
a bgp attribute to provide a service network wide, you have to explicitly 
specify that desire...
br,
cs
