Enable IPv6
Default IPv6 di disable. Cek melalui,
/system package print

IP addressing
Menambahkan IP address ke interface.

Buat BGP ingress Filter
Ingress filters are used to filter advertisements into the network. Best practice for ingress filters for all peers are:
Discard receiving ones own prefix Discard receiving a default route as we are doing full routing Discard special purpose address registry entries stated at RFC 6890.
Chain IN-IXP-IPv4 is an input filter and it discards receiving ones own prefix or a default route as full routing is taking place. This filter jumps to a further chain IN-RFC-6890-IPv4 that discards IPv4 Special-Purpose Address Registry Entries stated at RFC 6890.
routing filter add chain=IN-IXP-IPv4 prefix=199.2.2.0/24 action=discard routing filter add chain=IN-IXP-IPv4 prefix=0.0.0.0/0 action=discard routing filter add chain=IN-IXP-IPv4 action=jump jump-target=IN-RFC-6890-IPv4 routing filter add chain=IN-RFC-6890-IPv4 prefix=0.0.0.0/8 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=10.0.0.0/8 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=100.64.0.0/10 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=127.0.0.0/8 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=169.254.0.0/16 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=172.16.0.0/12 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=192.0.2.0/24 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=192.88.99.0/24 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=192.168.0.0/16 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=198.18.0.0/15 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=198.51.100.0/24 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=203.0.113.0/24 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=240.0.0.0/4 action=discard routing filter add chain=IN-RFC-6890-IPv4 prefix=255.255.255.255/32 action=discard
Chain IN-IXP-IPv6 is an input filter and it discards receiving ones own IPv6 prefix or a default route as full routing is taking place. This filter jumps to a further chain IN-RFC-6890-IPv6 that discards IPv6 Special-Purpose Address Registry Entries stated at RFC 6890.
routing filter add chain=IN-IXP-IPv6 prefix=2a99:2:2::/48 action=discard routing filter add chain=IN-IXP-IPv6 prefix=::/0 action=discard routing filter add chain=IN-IXP-IPv6 action=jump jump-target=IN-RFC-6890-IPv6 routing filter add chain=IN-RFC-6890-IPv6 prefix=::1/128 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=::/128 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=64:ff9b::/96 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=::ffff:0:0/96 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=100::/64 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=2001::/23 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=2001::/32 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=2001:2::/48 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=2001:db8::/32 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=2001:10::/28 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=2002::/16 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=fc00::/7 action=discard routing filter add chain=IN-RFC-6890-IPv6 prefix=fe80::/10 action=discard
Buat BGP egress Filters
Egress filters are used to filter advertisements from the network, limiting it to only advertise the specific local networks. Note the invert-match=yes statement, this instructs the filter to discard all but the prefix specified.
routing filter add chain=OUT-IPv4 prefix=199.2.2.0/24 invert-match=yes action=discard routing filter add chain=OUT-IPv6 prefix=2a99:2:2::/48 invert-match=yes action=discard
Tambahkan BGP Peer
Create the peer links to the other BGP peers for IPv4 and IPv6. Note that IPv4 family is the default and for IPv6 the family must be specified.
routing bgp peer add name=ixp instance=ASN5222 remote-as=5999 remote-address=199.9.9.1 in-filter=IN-IXP-IPv4 out-filter=OUT-IPv4 routing bgp peer add name=ixp instance=ASN5222 remote-as=5999 remote-address=2a99:9:9::1 address-families=ipv6 in-filter=IN-IXP-IPv6 out-filter=OUT-IPv6
