    • Confederations • Proxy ARP Refer to the 7450 ESS, 7750 SR, and VSR Triple Play Service Delivery Architecture Guide for information about DHCP and support as well as configuration examples for the 7750 SR and 7450 ESS. 2.1.1 Interfaces Nokia routers use different types of interfaces for various functions.
  • Page 16: Network Domains

    IP Router Configuration ROUTER CONFIGURATION GUIDE RELEASE 15.0.R5 • Physical or logical port • A SONET/SDH channel for the 7750 SR or 7450 ESS 2.1.1.2 Network Domains To determine which network ports (and, therefore, which network complexes) are eligible to transport traffic of individual SDPs, network-domain is provided. Network- domain information is then used for the sap-ingress queue allocation algorithm applied to VPLS SAPs.
  • Page 17: System Interface

    ROUTER CONFIGURATION GUIDE IP Router Configuration RELEASE 15.0.R5 Any SDP can be assigned only to one network domain. If none is specified, the system will assign the default network-domain. This means that all SAPs in VPLS will have queue reaching all fwd-complexes serving interfaces that belong to the same network-domains as the SDPs.
  • Page 18: Creating An Ip Address Range

    IP Router Configuration ROUTER CONFIGURATION GUIDE RELEASE 15.0.R5 In loose mode, uRPF checks whether the incoming packet has a source address that matches a prefix in the routing table; loose mode does not check whether the interface expects to receive a packet with a specific source address prefix. Loose mode uRPF check is supported for ECMP, IGP shortcuts, and VPRN MP-BGP routes.
  • Page 19: Qos Policy Propagation Using Bgp (Qppb)

    This section describes QPPB as it applies to VPRN, IES, and router interfaces. Refer to the “Internet Enhanced Service” section in the 7450 ESS, 7750 SR, 7950 XRS, and VSR Layer 3 Services Guide: IES and VPRN and the “IP Router Configuration”...

  • Page 177 ROUTER CONFIGURATION GUIDE IP Router Configuration RELEASE 15.0.R5 Description This command configures the TTL propagation for locally generated packets which are forwarded over a BGP label route in the Global Routing Table (GRT) context. For IPv4 and IPv6 packets forwarded using a RFC 3107 label route in the global routing instance, including 6PE, the all value of the command enables TTL propagation from the IP header into all labels in the transport label stack.
  • Page 178 IP Router Configuration ROUTER CONFIGURATION GUIDE RELEASE 15.0.R5 The TTL of the IP packet is always propagated into the RFC 3107 label itself, and this command only controls the propagation into the transport labels, for example, labels of the RSVP or LDP LSP to which the BGP label route resolves and which are pushed on top of the BGP label.
  • Page 179 ROUTER CONFIGURATION GUIDE IP Router Configuration RELEASE 15.0.R5 The none value reverts to the default mode which disables TTL propagation. This changes the existing default behavior which propagates the TTL to the transport label stack. When a customer upgrades, the new default becomes in effect. This command does not have a no version.
  • Page 180 IP Router Configuration ROUTER CONFIGURATION GUIDE RELEASE 15.0.R5 The default behavior for a given VPRN instance is to inherit the global configuration for the same command. The user can explicitly set the default behavior by configuring the inherit value. When a packet is received in a VPRN context but is looked up in the Global Routing Table (GRT), for example, leaking to GRT is enabled, the behavior of the TTL propagation is governed by the RSVP or LDP shortcut configuration when the matching routing is a LSP shortcut route.
