AppleTalk Routing

HP routing switches support Phase II AppleTalk routing. HP's implementation supports all the following AppleTalk
protocols:
EtherTalk Link Access Protocol (ELAP) – AppleTalk physical layer protocol
Datagram Delivery Protocol (DDP) – AppleTalk equivalent of IP/UDP
AppleTalk Echo Protocol (AEP) – AppleTalk equivalent of IP/ICMP
AppleTalk Transaction Protocol (ATP) – AppleTalk equivalent of IP/TCP
NOTE: A sub-set of ATP is implemented to support ZIP on HP routing switches.
Name Binding Protocol (NBP) – AppleTalk equivalent of IP/DNS
AppleTalk Zone and Network Filters
Zone filters and network filters enable you to control access to AppleTalk networks and individual nodes:
Zone filters – Explicitly permit or deny access to specific zones on specific ports
Network filters – Explicitly permit or deny access to specific networks on specific ports
IP Multicast Routing (PIM and DVMRP)
Multicast protocols allow a group or channel to be accessed over different networks by multiple stations (clients)
for the receipt and transmit of multicast routing. Distribution of stock quotes, video transmissions, such as news
services or remote classrooms and video conferencing, are all examples of multicast routing.
HP routing switches support the following IP multicast protocols:
Distance Vector Multicast Routing Protocol (DVMRP) – a broadcast and pruning multicast protocol that
delivers IP multicast datagrams to its intended receivers.
Internet Group Membership Protocol (IGMP) – a protocol used by DVMRP routers to advertise multicast
groups to the routers that are distributing the multicasts.
Protocol Independent Multicast (PIM) protocol – an alternative to DVMRP that uses the routing switch's IP
route table rather than maintaining a separate multicast route table as DVMRP does. Dense and Sparse
modes are supported.
The Multicast Source Discovery Protocol (MSDP) – a protocol used by PIM Sparse routers to exchange
routing information for PIM Sparse multicast groups across PIM Sparse domains. Routers running MSDP
can discover PIM Sparse sources that are in other PIM Sparse domains. PIM Sparse routers use MSDP to
register PIM Sparse multicast sources in a domain with the Rendezvous Point (RP) for that domain.
DVMRP and PIM can concurrently operate on different ports of an HP routing switch.
For both versions of IP multicast, HP routing switches support IP tunneling. IP tunneling allows HP routing
switches that are performing IP multicast to send multicast traffic through routers that do not support either PIM or
DVMRP multicasting.
For more details on configuring the HP routing switches for IP multicast, see the "Configuring IP Multicast
Protocols" chapter in the Advanced Configuration and Management Guide.
Redistribution Filters
HP routing switches allow you to configure parameters for redistributing routes among the following routing
protocols:
IP/RIP
IP/OSPF
IP/BGP4
