bgpd: cli for SRv6 SID alloc to redirect to vrf (step4)
This commit add cil to configure BGP SRv6-VPN sid allocation.
Almost mechanism are based on BGP MPLS-VPN.
User can allocate and export sid with using following config.
Then bgpd try to allocate new SID to redirect vpn to vrf using
SRv6 localsid End.DT4/DT6. Currently linux kernel will regect
End.DT4 route install due to no-implementation.
(at-least today's FRR's ci kernel.)
So now we only supports BGP SRv6-VPNv6.
router bgp 1
segment-routing srv6
locator loc1
!
address-family ipv6 vpn
exit-address-family
!
router bgp 1 vrf vrf10
address-family ipv6 unicast
sid vpn export 1 !!(option1)!!
sid vpn export auto !!(option2)!!
exit-address-family
