IPv4 redistribution Supported platform: OS6800, OS6850, and OS9000
IPv4 Redistribution instances use route-maps to redistribute routes from a source protocol RIB to a
destination protocol RIB. The source protocol can be BGP, RIP, OSPF, Local or Static. The
destination protocol can be BGP, RIP or OSPF.
The following values are the tested limits with the functionally verified (stress test).
• Tested number of route-maps that can be created on router: 200
• Tested number of route-map sequences that can be created on router: 400
• Tested number of IPv4 access-lists that can be configured on router: 200
• Tested number of OSPFv2 routes that can be redistributed into RIPv2: 8.5K
• Tested number of RIPv2 routes that can be redistributed into OSPFv2: 8K

PIM-DM (IPv4)
Note: IPv6 PIM-DM will be supported in a
future Release
PIM-DM is a multicast routing protocol that defines a multicast routing algorithm for multicast groups
that are densely distributed across a network. It uses the underlying unicast routing information base to
flood multicast datagrams to all multicast routers. Prune messages are used to prevent future messages
from propagating to routers with no group membership information. It employs the same packet
formats as sparse mode PIM (PIM-SM).
PIM-DM assumes that when a multicast source starts sending, all downstream systems want to receive
multicast datagrams. Initially, multicast datagrams are flooded to all areas of the network. PIM-DM
uses RPF (Reverse Path Forwarding) to prevent looping of multicast datagrams while flooding. If
some areas of the network do not have group members, PIM-DM will prune off the forwarding branch
by instantiating prune state.
PIM-DM differs from PIM-SM in two essential ways:
1. There are no periodic joins transmitted, only explicitly triggered prunes and grafts.
2. There is no Rendezvous Point (RP). This is particularly important in networks that cannot tolerate a
single point of failure.
IGMP learning performance The system can process 1000 IGMP per second.
However, the performance can drop to 128 when IGMP are received too fast.
• Burst of 1000 IGMP reports at 1000 packet/sec: all 1000 groups are learnt
• Burst of 1000 IGMP reports at 1Gbps: only 128 groups are learnt
Zapping You can configure “ip multicast zapping” to optimize channel surfing. That will instantly stop
forwarding multicast to a client when that client sent an IGMP Leave. The zapping time can be
measured by the leave message received by the switch and the last packet received by the client. This
is usually in milliseconds. The feature is well suited for Multicast Switching and zapping only works
well when “ip multicast querying” is disabled.
L2 static multicast •1022 static multicast MACs are supported on OS6850 and OS9000. The L2 Multicast table can have
1024 entries but 2 are reserved for other applications.
