interface TTL
For CoreBuilder 9000: Applies to Layer 3 switching modules only.
Modifies the time-to-live (TTL) threshold of a given routing interface. The
interface compares the TTL value in each IP multicast packet against its
TTL threshold. If the packet TTL is greater than the threshold TTL, the
interface decrements the packet TTL by 1 and forwards the packet,
provided that no other restrictions exist.
Valid Minimum Abbreviation
ip m i i t
Important Considerations
■
Because IGMP is enabled by factory default, the system assigns a TTL
threshold value of 1 as soon as you create an IP interface.
■
This TTL threshold affects IP multicast packets only.
