Configuring IPv6 IS-IS single topology
The following configuration tasks are optional:
• Configure IPv6 route parameters.
• Redistribute routes from other route sources into IPv6 IS-IS.
• Perform IPv6 IS-IS adjacency checks.
• Disable partial SPF calculations.
Configuring IPv6 IS-IS single topology
If your IS-IS single topology will support both IPv6 and IPv4, you can configure both IPv6 and IPv4
on an IS-IS interface for Level 1, Level 2, or both Level 1 and Level 2. However, if you configure both
IPv6 and IPv4 on an IS-IS interface, they must be configured to run on the same level. For example,
you can configure IPv6 to run on Level 1 on an interface and IPv4 to also run on Level 1 on the
same interface. However, you cannot configure IPv6 to run on Level 1 on an interface and IPv4 to
run to Level 2 on the same interface.
To configure an IPv6 IS-IS single topology, you must perform the tasks listed below.
1. Globally enable IS-IS and configure at least one Network Entity Title (NET). The NET is the
device’s network interface with IS-IS. You can configure up to three NETs on a device.
2. Configure the desired device interfaces with an IPv6 address and enable IPv6 IS-IS on the
device interfaces.
3. Configure IS-IS parameters. Refer to the sections “Globally configuring IS-IS on a device” on
page 714, “Configuring IPv6 specific address family route parameters” on page 715, and
“Configuring IS-IS properties on an interface” on page 723.
Globally configuring IS-IS on a device
The following configuration tasks described in Chapter 3, “IS-IS (IPv4)” , apply to IS-IS IPv6
configuration:
• Setting the Overload Bit
• Configuring Authentication
• Changing the IS-IS Level Globally
• Disabling or Re-enabling Display of Hostname
• Changing the Sequence Numbers PDU Interval
• Changing the Maximum LSP Lifetime
• Changing the LSP Refresh Interval
• Changing the LSP Generation Interval
• Changing the LSP Interval and Retransmit
• Changing the SPF Timer
• Globally Disabling or Re-Enabling Hello Padding
• Logging Adjacency Changes
• Disabling Partial SPF Calculations
