Layer 3 enhancements (Continued)
Description
In this release, if a default route is not present in
the IP routing table, the user can configure a
major route to be used for forwarding packets to
all unknown destination. Starting with release
02.3.00a.
With this release of Multi-Service IronWare, the
process by which BGP selects a path has
changed. The following procedure replaces the
procedure described in the BigIron RX Series
Configuration Guide.
The allowas-in command has been added to this
release to allow you to set a parameter that
disables the BGP AS_PATH check function for
routes learned from a specified location.
This feature allows for load distribution of traffic
among the available default route next-hops.
The Transparent Firewall mode feature allows
users to insert a Firewall in front of their existing
network without changing the statically defined
IP addresses of their network-connected devices.
This will allow the users to permit selected
devices from a subnet to cross the firewall while
access to other devices on the same subnet are
denied.
IP multicast enhancements
Description
Multiprotocol BGP allows for the inclusion of
information other than IPv4 routes through
BGP packets is available in this release.
This release supports the Multicast Source
Discovery Protocol (MSDP). It is used by
Protocol Independent Multicast (PIM) Sparse
routers to exchange routing information for
PIM Sparse multicast groups across PIM
Sparse domains.
