[Xorp-users] Multicast over GRE tunnel between Cisco and Ubuntu 11.10

[Thiago Anderson]

Ben,

Thanks for helping the tunnel is booming .... hehehe multicast is ok ... to
anyone who want the setup done .... follows...

So details for the tunnel is a gre ipsec with:

Configuring ipsec with openswan:
conn tunnel00
        type=tunnel
        connaddrfamily=ipv4
        authby= secret
        left=your_net_ip
        leftnexthop=your_net_gw
        leftsubnet=ip_linux/32
        leftsourceip=source_ip
        rightsourceip=ip_cisco/32
        right=ip_cisco_net
        rightsubnet=ip_cisco/32
        ike=3des-md5,3des-sha-modp1024
        phase2alg=3des-md5-96,3des-sha1
        keyexchange=ike
        pfs=no
        auto=add
        rightid=ip_cisco_net
        leftid=your_net_ip


GRE tunnel configuration:

modprobe ip_gre
ip tu ad gre00 mode gre local ip_linux/32 remote ip_cisco/32 dev
internet_eth
ip ad ad dev gre00 ip_gre_linux peer ip_gre_cisco/30
ip li se dev gre00 up
ifconfig gre00 multicast

XORP configuration, installed from github:

eth2 is the network interface
gre00 is the gre tunnel

protocols {
        igmp {
                interface gre00 {
                        vif gre00 {

                        }
                }
                interface eth2 {
                        vif eth2 {

Thanks for everything once again, was about changing my fw linux for a
cisco router ... :)
