• Contents of the Binding Update
• The prefix of the mobile link. But is it needed
  
• in the BU? (all information related to routing
  is
• present at the HA/BR when the MR is at home)
• The home address which is a link-local address
  of
• the egress interface, but issues with Mobile
  IPv6

• HA needs a way to acquire routes towards
• the mobile network link
• Manually configured on the HA
• Dynamically configured on the HA
• ICMP Redirects

Does NEMO WG also want to consider scenario 2?
6

• MR and Multicast
• LFNs continue to receive their multicast
  sessions
• MR continues its multicast subscriptions as if
• it were at home

7

• Neighbour Discovery for MR
• MR acquires CoA in Foreign Network listen RAs
• Issue Potentially 2 default routes
• MRHA tunnel (must be used)
• 1 auto-configured from RA
• MR at home should not advertise itself as
  default
• router on the egress interface
• MR in the foreign net should not reply to RSs
• received on the egress interface

8

• Other Issues from the Mailing List
• Check Table on the HA offering possibility of
• security checks, to counter certain threats.
• MRs belonging to the same HA are administered
• by the same entity, or by different entities.
  Important
• security threats.
