IPv6

Route map actually prohibits machine -> machine connection due to:

Turns out the match expression differs between ip and ipv6, with this route-map it works:

 !
 address-family ipv4 unicast
  redistribute connected
  neighbor MACHINE maximum-prefix 24000
  neighbor MACHINE route-map vrf30-in in
 exit-address-family
 !
 address-family ipv6 unicast
  redistribute connected
  neighbor MACHINE maximum-prefix 24000
  neighbor MACHINE route-map vrf30-in6 in
  neighbor MACHINE activate
 exit-address-family
 !
 address-family l2vpn evpn
  advertise ipv4 unicast
  advertise ipv6 unicast
 exit-address-family
!
ip prefix-list vrf30-in6-prefixes seq 12 permit 2002::/64 le 128
route-map vrf30-in6 permit 10
 match ipv6 address prefix-list vrf30-in6-prefixes <-- match ipv6
!
# route-maps for vrf30
ip prefix-list vrf30-in-prefixes seq 10 permit 10.0.0.1/32 le 32
ip prefix-list vrf30-in-prefixes seq 11 permit 10.0.4.1/32 le 32
ip prefix-list vrf30-in-prefixes seq 13 permit 10.244.0.0/16 le 32
route-map vrf30-in permit 10
 match ip address prefix-list vrf30-in-prefixes
