Scenario

The

Spacevars
0product
 enables full interworking between transmission protocols and bridging between IPv4/IPv6 domains.

Background Information

  • The requirements specified in the section "Background Information and Dependencies" under Minimal Out-Of-The-Box Configuration are met.
  • Ports and IP Interface Groups have been configured as described in NNI: Complex route selection.
  • At the NNI/Peering edge the number of direct peers is much lower than the access edge and therefore it is much more reasonable to expect the
    Spacevars
    0product
    to be able to maintain simultaneous TCP connections for any peers that are using these protocols. Connections can still be dynamically established as required and are recycled if idle in order to free up resources for other users
