Release Notes for Cisco IOS Release 12.0 S

78-7130-11 Rev. B0

New and Changed Information

MPLS over Frame Relay

Platforms: Cisco 7200 series, Cisco 7500/RSP series

Transmission of Multiprotocol Label Switching (MPLS)-encapsulated packets across a point-to-point

Frame Relay subinterface is now supported. Configuration of the feature is identical to configuration of

MPLS on any other interface type:

(config)# interface Serial1/0.1 point-to-point

(config-if)# tag ip

(config-if)# mpls traffic-engineering tunnels

Note that some Frame Relay features (for example, FRF.12 fragmentation) are not supported for MPLS

packets.

Named Community Lists

Platforms: Cisco 7200 series, Cisco 7500/RSP series, Cisco 12000 series

With numbered community lists, there are two types of community list numbers (standard and

extended), and there can be up to 100 of each of the lists. Named community lists do not have an upper

limit on the number of lists that can be defined. The command syntax is as follows:

ip community-list standard [community-name | community-number] [permit|deny] community

ip community-list extended [community-name | community-number] [permit|deny]

regular-expression

All rules of numbered community lists apply.

Secure Shell Client Version 1

Platforms: Cisco 7200 series, Cisco 7500/RSP series, Cisco 12000 series

Secure Shell (SSH) is a protocol that provides a secure, remote connection to a router. Two versions of

SSH are available: SSH Version 1, and SSH Version 2. Only SSH Version 1 is implemented in

Cisco IOS software.

The SSH Server feature enables a SSH client to make a secure, encrypted connection to a Cisco router.

This connection provides functionality that is similar to an inbound Telnet connection. The SSH server

in Cisco IOS software will work with publicly and commercially available SSH clients.

The SSH Client feature is an application that runs on a reliable TCP/IP transport layer, and provides

strong authentication and encryption. The SSH Client in Cisco IOS software allows a user that is

running an EXEC session on a Cisco router to log in to another remote Cisco router, and execute

commands on the remote router. With authentication and encryption, SSH Client allows for a secure

communication over an insecure network. SSH Client Version 1 supports DES and 3DES encryption

and userid/password authentication.
