Inter Chassis Session Recovery

38

• Provides 1:1 redundancy in case of failures

• Uses propriety Service Redundancy Protocol (SRP) over TCP link

• Needs a separate context for SRP

• Configuration must be identical

• Tasks peers between two chassis

• Session states are synchronized between the chassis pair

• Session states checkpoint starts after 60 seconds for call establishment

Implementing Cisco Service Provider Next-Generation

Core Network Services (SPCORE)

Edge Network Services (SPEDGE)

SPROUTE covers the implementation of routing protocols (OSPF, IS-IS, BGP),

route manipulations, and HA routing features; SPADVROUTE covers advanced

routing topics in BGP, multicast services including PIM-SM, and IPv6;

SPCORE covers network services, including MPLS-LDP, MPLS traffic engineering,

QoS mechanisms, and transport technologies;

SPEDGE covers network services, including MPLS Layer 3 VPNs, Layer 2 VPNs,

and Carrier Ethernet services; all within SP IP NGN environments.
