PowerConnect 6224/6224F/6224P/6248/6248P Release Notes

¾Configured Tunnels MTU

To comply with RFC 4213, Basic Transition Mechanisms for IPv6 Hosts and Routers, the IPv6 MTU on configured IPv6 over IPv4 tunnels was changed from 1480 bytes to 1280 bytes.

¾IPv6 6 to 4 Auto Tunnels

The 6 to 4 tunnels automatically formed IPv4 6 to 4 tunnels for carrying IPv6 traffic. The automatic tunnel IPv4 destination address is derived from the 6 to 4 IPv6 address of the tunnel next hop. There is support for a 6 to 4 border router that connects a 6 to 4 site to a 6 to 4 domain. It sends/receives tunneled traffic from routers in a 6 to 4 domain that includes other 6 to 4 border routers and 6 to 4 relay routers.

¾VRRP Route Interface Tracking

This extends the capability of the Virtual Router Redundancy Protocol (VRRP) to allow tracking of specific route/interface IP state within the router that can alter the priority level of a virtual router for a VRRP group.

The exception to this is, if that VRRP group is the IP address owner, its priority is fixed at 255 and can not be reduced through tracking process.

¾ICMP Throttling

This adds configuration options for the transmission of various types of ICMP messages. This project adds the following configuration options:

Rate limiting the generation of ICMP error messages.

Suppression of ICMP echo replies.

Suppression of ICMP Redirects.

Suppression of Destination Unreachables.

¾IP Helper

Provides the ability to enable DHCP relay on specific interfaces, with DHCP server addresses specified independently on each interface. The ip helper-addresscommands configure both DHCP and UDP relay.

¾OSPF Enhancements

A CLI command is added with options to do the following:

Disable and re-enable OSPF

Clear the OSPF configuration

Bounce all or specific OSPF neighbors

Flush and re-originate all self-originated external LSAs

Clear OSPF statistics

¾Support of IPv6 routes in PIM-SM and PIM-DM

Support for IPv6 routes has been added to PIM-SM and PIM-DM.
