AW: [support] multihoming does not work

[Trinks, Marcus (K-EFFI)]

I would like to mention that MIP works now with two interfaces. But I could not really figure out
why it doesent work before since I didnt change the config files.
 
best regards
 
Marcus

Betreff: [support] multihoming does not work




Dear nautilus6 community, 
I have set up a MIP testbed based on 2.6.24-1-mip6-686. Mobility with one egress interface on the mobile router 
works fine. But when i try to add a second interface I cannot register the mobile router with the second interface 
to the home agent. 
My mip6d.conf at the mobile router looks as follows: 
      # This is an example of mip6d NEMO enabled Mobile Router configuration file 
   NodeConfig MN; 
   DebugLevel 10; 
   DoRouteOptimizationCN disabled; 
   DoRouteOptimizationMN disabled; 
   UseCnBuAck disabled; 
  
   # Explicit Modus an 
   MobRtrUseExplicitMode enabled; 
  
   # Optimierte Handover eingeschaltet 
   OptimisticHandoff enabled; 
   
   # The Binding Lifetime in Sekunden 
   MnMaxHaBindingLife 60; 
  
   # ethX durch das Egress Interface ersetzen 
   # (Das ist das Interface welches mit dem Home Link oder Foreign Link verbunden ist) 
   Interface "eth1" { 
        MnIfPreference 1; 
        IfType MN; 
                    } 
   Interface "eth2" { 
        MnIfPreference 2; 
        IfType MN; 
                    } 
   # Ersetze eth0 durch das Egress Interface 
   MnHomeLink "eth1" { 
        IsMobRtr enabled; 
        HomeAgentAddress 2001:1:1:0::1000; 
        HomeAddress 2001:1:1:0::1/64 (2001:1:1:1::/64); 
                     } 
  
   # IPsec Konfiguration - Momentan nicht unterstützt 
   UseMnHaIPsec disabled; 
   KeyMngMobCapability disabled; 
   #EOF 

My startupskript at the mobile router is like this: 
   #!/bin/bash 
   # Mobile Router MR - Startup script 

	# Interface definition 
	IF1=eth1 
	IF2=eth0 
	# Put here the path to your radvd binary 
	RADVD=/usr/sbin/radvd 
	# Put here the path to your mip6d binary 
	NEMOD=/usr/sbin/mip6d 
	# Deny RA and setup forwarding 
	echo 0 > /proc/sys/net/ipv6/conf/all/accept_ra 
	echo 1 > /proc/sys/net/ipv6/conf/all/forwarding 
	# IF1 is the egress interface. Do not configure any address on it. 
	ifconfig $IF1 up 
	# IF2 is the ingress interface, connected to the NEMO-Link 
	ifconfig $IF2 up 
	ifconfig $IF2 inet6 add 2001:1:1:1::1/64 
	# IF3 ist das zweite Egress Interface 
	ifconfig $IF3 up 
	# Execute the router advertisement daemon 
	$RADVD -C /etc/radvd.conf 
	# Execute the NEMO daemon 
	$NEMOD -c /etc/mip6d.conf 

The mip6d.conf at the home agent ist the following: 
      # This is an example of mip6d NEMO enabled Home Agent configuration file 
   NodeConfig HA; 
   # Set DebugLevel to 0 if you do not want debug messages 
   DebugLevel 10; 
   # Replace eth1 with the interface connected to the HOME LINK 
   Interface "eth1"; 
   HaAcceptMobRtr enabled; 

   # MNP configuration 
   HaServedPrefix 2001:1:1:0::/64; 
   BindingAclPolicy 2001:1:1:0::1 (2001:1:1:1::/64) allow; 
   BindingAclPolicy 2001:1:1:0::2 (2001:1:1:1::/64) allow; 
   DefaultBindingAclPolicy allow; 

   # IPsec configuration - NO IPSEC AT THE MOMENT 
   UseMnHaIPsec disabled; 
   KeyMngMobCapability disabled; 
   # EOF 

Would be great if somebody could give me support. Thanks a lot. 
Thanks a lot in advanced. 

best regards, 
Marcus
