Abilene[] is another project of UCAID. It's complementary to Internet2 in the sense that the main goal of Abilene is to provide a primary backbone network for the Internet2 project. UCAID, in partnership with Qwest Communications, Nortel Networks, and Cisco Systems, has developed the Abilene network. Abilene provides the high-performance interconnect services among the Internet2 regional aggregation points. The primarily OC48c (2.5 Gbps) POS (Packet Over SONET) Abilene netw..
Interdomain Multicast: MSDP and MBGP
How do RPs learn about sources in other PIM domains? This problem is solved by the Multicast Source Discovery Protocol (MSDP). At the time of this writing, MSDP was still an Internet draft, and therefore this section describes only a work-in-progress. MSDP uses simple, one-to-one, BGP-like peering sessions to establish communication between RPs. Unlike BGP, however, no connection collision mechanism exists. Instead, the peer with the higher address listens on TCP port..
PIX and ASA Feature and Product Overview
In the next two sections, I'll discuss briefly some of the VPN features and VPN capabilities of the PIX and ASA security appliances. This information can help you in determining if the PIX or ASA is the right product platform for you, and which PIX or ASA appliance you should choose for a VPN implementation. PIX and ASA VPN Features Cisco PIX and ASA security appliances support many VPN features. They are fully IPsec-compliant and support both L2L and remote access services..
Most of the features mentioned in the previous section are Cisco IOS features and pertain to employing CAC when Cisco IOS voice gateway routers connect traditional telephony equipment into an IP network. Much of the voice traffic in VoIP networks, however, originates from IP phones, not from gateways, and none of these features (other than potentially RSVP) applies to traffic from these devices. Therefore, Cisco CallManager has additional CAC features to cover the management..
MPLS Traffic Engineering with Autoroute
This recipe uses Cisco's Autoroute feature for managing Traffic Engineering (TE) with OSPF in an MPLS network. For this method, we must explicitly define all of the traffic paths and associate them with Tunnels on the PE routers: Router-PE1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router-PE1(config)#mpls traffic-eng tunnels Router-PE1(config)#interface Loopback0 Router-PE1(config-if)#ip address 10.0.0.2 255.255.255.255 Router..
