  • Page 39: Rep

    Layer 2 Solution REP ▀ The Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to the Spanning Tree Protocol (STP). REP provides a way to control network loops, handle link failures, and improve convergence time. It controls a group of ports connected in a segment, ensures that the segment does not create any bridging loops, and responds to link failures within the segment.

  • Page 45: Chapter 3 Basic Mpls Vpn Configuration

    Configuration of OSPF and BFD OSPF is chosen as IGP protocol and BFD is used to detect link failure for fast convergence. ASR 903 supports both software and hardware based BFD sessions. When a BFD session is created, depending on the hardware resources and nature of BFD session, it can be offloaded to hardware.

    Configuration for BGP PIC & RFC3107 (with ISIS) ▀ Chapter 10 Cisco ASR 903 supports three level hierarchical QoS, port, vlan and class level. Classification, marking, policing, shaping and LLQ are supported. At class level, you can have up to 8 classes including class-default under a policy- map.
  • Page 128 As a best practice, it is recommended to mark ingress packets into internal qos-group and then take action based on those qos-groups. Qos-groups are internal entities on the router and there are 100 usable qos-groups. ▄ Cisco ASR 903 Router Design and Deployment Guide OL-30526-01...

    ISSU One Shot Upgrade Overview The ISSU one shot update is the preferred method of updating software on a dual RSP ASR 903 system. The one shot update is designed to operate optimally when the router is booted in sub-package mode. In this mode, the router will perform rolling upgrades of interface module software (and firmware if applicable).
