DXS-3610 Series Layer 3 Stackable 10GbE Managed Switch Web UI Reference Guide Parameter Metric Style Set Overload Bit On Startup Suppress SPF Interval Level-1 SPF Interval Level-2 VRF Name Description Select the metric style here. This is used configure the ISIS process generation and metric style acceptation. Options to choose from are: Narrow - Specifies to generate old-style metric TLVs. Wide - Specifies to generate new-style metric TLVs. Narrow Transition - Specifies to generate old-style metric TLVs and to accept both old and new-style metric TLVs. Wide Transition - Specifies to generate new-style metric TLVs and to accept both old and new-style metric TLVs. Transition - Specifies to generate both old and new-style metric TLVs. Also for each metric style, the level can be selected. Options to choose from are:  Level-1 - Specifies to enable this only on level 1 routing.  Level-1-2 - Specifies to enable this on both level 1 and level 2 routing.  Level-2 - Specifies to enable this only on level 2 routing. Select to enable or disable the set overload bit feature here. This is used to force the ISIS process to set the overload bit in its non-pseudo node LSPs. Normally, the setting of the overload bit is allowed only when a router runs into problems. For example, when a router is experiencing a memory shortage, it might be that the LSPDB isn't complete, resulting in an incomplete or inaccurate routing table. By setting the overload bit in its LSPs, other router can ignore the unreliable router in their SPF calculations until the router has recovered from its problems. Enter the set overload bit on startup time value here. This specifies to configure the overload bit upon the system when starting up. The overload bit remains configured for the number of seconds specified. The range is from 5 to 86400 seconds. Select the suppress option here. This specifies that the type of prefix identified by the subsequent keyword or keywords will be suppressed. Options to choose from are:  None - Specifies that it will not prevent any IP prefixes learned from another ISIS level and from other protocols from being advertised.  Interlevel - Specifies that it will prevent the IP prefixes learned from another ISIS level from being advertised.  External - Specifies that it will prevent the IP prefixes learned from other protocols from being advertised.  Both - Specifies that it will prevent the IP prefixes learned from another ISIS level and from other protocols from being advertised. Enter the SPF interval level-1 value here. This is used to customize ISIS throttling of SPF calculations applied to level-1 areas only. The range is from 1 to 120 seconds. Select the Default option to use the default value. Enter the SPF interval level-2 value here. This is used to customize ISIS throttling of SPF calculations applied to level-2 areas only. The range is from 1 to 120 seconds. Select the Default option to use the default value. Click the Please Select button to select a pre-configured VRF instance that will be used here. Select the No VRF option to specify that no VRF instance will be used here. Click the Apply button to accept the changes made. Click the Back button to return to the previous window. 392
