6.4 Configuration Examples
The following section provides an example for configuring GR. Familiarize yourself with the
configuration procedures against the networking diagram. The configuration example consists
of the networking requirements, configuration roadmap, configuration procedures, and
configuration files.
Context
NOTE
This document takes interface numbers and link types of the NE40E-X8 as an example. In working
situations, the actual interface numbers and link types may be different from those used in this document.
6.4.1 Example for Configuring the System-Level GR
In this example, by being enabled with GR, a device can ensure the uninterrupted forwarding
during the AMB/SMB switchover after a fault occurs on the device.
Networking Requirements
NOTE
POS interfaces cannot be configured on the X1 and X2 models of the NE80E/40E.
shows a networking diagram of configuring the system-level GR.
l
In AS65009, OSPF is used as the IGP protocol; an EBGP connection is set up between
Router A and Router B; Router C is a non-BGP device in the AS.
l
Router B has dual main control boards. The AMB and the SMB back up each other, and
support HSB. That is, the AMB and the SMB are configured with the HSB function.
l
BGP GR is enabled on Router A; OSPF GR and BGP GR are enabled on Router B; and
OSPF GR is enabled on Router C.
When Router B performs the AMB/SMB switchover triggered by the system fault or the
administrator, it is required that the service is not interrupted, that is, the current network service
is not affected.
