Tunnel interface

auto marla-ipv6-spn
iface marla-ipv6-spn inet6 v4tunnel
	mode ipip
	ttl 225
	address 2001:67c:21bc:7fff:0001:2:0:2
	netmask 120

	endpoint 79.98.105.18

In this example, 2001:67c:21bc:7fff:2:1:0:1 and 2001:67c:21bc:7fff:2:1:1:1 are the remote end-points of the tunnels, 2001:67c:21bc:4::/62 is the assigned network, and 65535 is the ASN delegated to this peer.

Basically, this configuration says "connect to the two peers, and filter what I announce to them to be just my own network".

(this is actually the live configuration of initLab)

# if you want to populate multiple routing tables with device routes.

# tables and the kernel. If your kernel supports multiple routing tables
# (as Linux 2.2.x does), you can run multiple instances of the kernel
# protocol and synchronize different kernel tables with different BIRD tables.

	learn;
	persist;
	scan time 20;
	export all;
}

# This pseudo-protocol watches all interface up/down events.

        if (net = 2001:67c:21bc:4::/64 ) then accept;
        else reject;
}

template bgp t_ext_ip6 {
	# replace ASN here!
        local as 65532;
        export filter ext_originate_ip6;
