  • Page 100

    Parameters 1: Specifies the RIP version as RIPv1. 2: Specifies the RIP version as RIPv2. RIPv2 messages are multicast. Usage guidelines An interface prefers the RIP version configured on it over the global RIP version.

    Views OSPF view Predefined user roles network-admin Parameters interval: Specifies the interval that OSPF exits overflow state, in the range of 0 to 2147483647 seconds. Usage guidelines When the number of LSAs in the LSDB exceeds the upper limit, the LSDB is in an overflow state. In this state, OSPF does not receive any external LSAs and deletes the external LSAs generated by itself to save system resources.

  • Page 164: Lsdb-overflow-limit

    Usage guidelines When network changes are infrequent, LSAs are generated at the minimum-interval. If network changes become frequent, the LSA generation interval is incremented by incremental-interval × 2 (n is the number of generation times) for each generation until the maximum-interval is reached. The minimum interval and the incremental interval cannot be greater than the maximum interval.

    Usage guidelines If an interface receives no hello packet from a neighbor within the dead interval, the interface considers the neighbor down. The dead interval on an interface is at least four times the hello interval. Routers attached to the same segment must have the same dead interval. Examples # Configure the dead interval for VLAN-interface 10 as 60 seconds.

  • Page 273: Timer Spf

    Predefined user roles network-admin Parameters seconds: Specifies the LSP refresh interval in the range of 1 to 65534 seconds. Usage guidelines To prevent valid routes from aging out and to synchronize LSPs in the network, each router needs to refresh its LSPs at a configurable interval and send them to other routers. A smaller refresh interval speeds up network convergence but consumes more bandwidth.

  • Page 274: Virtual-system

    Usage guidelines Based on the LSDB, an IS-IS router uses the SPF algorithm to calculate a shortest path tree with itself being the root, and uses the shortest path tree to determine the next hop to a destination network. By adjusting the SPF calculation interval, you can prevent bandwidth and router resources from being overused due to frequent topology changes.

Because the third route's AS_PATH attribute contains AS number 65008 that does not belong to the confederation, BGP does not compare it with other routes. As a result, the first route becomes the optimal route.

    To modify the AS number of a peer, do not execute the peer as-number command repeatedly. Instead, you must first delete the peer and configure it again. After you create a peer, you must use the peer enable command to enable BGP to exchange routing information with the specified peer.

The device then sends an Open message to inform the peer that it does not support 4-byte AS numbers, so the BGP session can be established. If the peer device supports 4-byte AS numbers, do not enable the 4-byte AS number suppression function.

  • Page 365: Peer Default-route-advertise

    If a BGP router has multiple links to a peer, and the source interface fails, BGP has to reestablish TCP connections, causing network oscillation. To improve link availability, HP recommends that you use a loopback interface as the source interface.

Usage guidelines This command enables you to temporarily tear down the BGP session to a specific peer or peer group so that you can perform network upgrade and maintenance without needing to delete and reconfigure the peer or peer group.

  • Page 377: Peer Ipsec-profile

    Usage guidelines IMPORTANT: Ignoring the ORIGINATOR_ID attribute might introduce routing loops to the network. Do not use this command to ignore the ORIGINATOR_ID attribute if you are not sure there are no routing loops. By default, BGP drops incoming route updates whose ORIGINATOR_ID attribute is the same as the local router ID.

  • Page 378: Peer Keep-all-routes

    Usage guidelines IPsec can protect IPv6 BGP packets from data eavesdropping, tampering, and attacks caused by forged IPv6 BGP packets. When two IPv6 BGP neighbor devices, for example Device A and Device B, are configured with IPsec, Device A encapsulates an IPv6 BGP packet with IPsec before sending it to Device B. If Device B successfully receives and decapsulates the packet, it establishes an IPv6 BGP peer relationship with Device A or learns IPv6 BGP routes to Device A.

    Parameters interval interval: Specifies an interval at which an interface sends LSU packets, in the range of 10 to 1000 milliseconds. If the router has multiple OSPFv3 interfaces, increase this interval to reduce the total number of LSU packets sent by the router every second. count count: Specifies the maximum number of LSU packets sent by an interface at each interval, in the range of 1 to 200.

    Usage guidelines You can configure a virtual link to maintain connectivity between a non-backbone area and the backbone, or in the backbone itself. A virtual link is similar to an interface with OSPFv3 enabled. You can configure parameters such as hello, dead, retransmit and trans-delay for the virtual link. Both ends of a virtual link must be ABRs that are configured with the vlink-peer command.
