Some information in this chapter is device type specific. Devices in this chapter are categorized

depending on their IRF capability and support for interface cards that use independent processors for

forwarding traffic, as shown in Table 1.

Use undo debugging mfib to disable MFIB debugging.

Syntax

Centralized devices:

debugging mfib [ all-instance | vpn-instance vpn-instance-name ] { all | { driver | no-cache | packet |

undo debugging mfib [ all-instance | vpn-instance vpn-instance-name ] { all | { driver | no-cache |

packet | register | route | sync | upcall | wrong-iif } [ advanced-acl-number ] }

Distributed devices/centralized IRF devices:

debugging mfib [ all-instance | vpn-instance vpn-instance-name ] { all | { driver | no-cache | packet |
