Default no lsr-load-balancing
Parameters lbl-only — Only the label is used in the hashing algorithm.
lbl-ip — The IP header is included in the hashing algorithm.
ip-only — the IP header is used exclusively in the hashing algorithm
lsr-load-balancing
Syntax lsr-load-balancing { lbl-only | lbl-ip | ip-only }
no lsr-load-balancing
Context config>system
Description This command configures system-wide LSR load balancing. Hashing can be enabled on IP header at
an LSR for spraying labeled IP packets over multiple equal cost paths in ECMP in an LDP LSP and/
or over multiple links of a LAG group in all types of LSPs.
In previous releases, the LSR hash routine operated on the label stack only. However, this lacked the
granularity to provide hashing on the IP header if a packet is IPv4. An LSR will consider a packet to
be IPv4 if the first nibble following the bottom of the label stack is 4. This feature is supported for
IPv4 support only and on IOM-3 and IMMs only. IPv6 packets are hashed on label stack only. The
hash on label and IPv4 header can be enabled or disabled at the system level only.
Default
disabled
mac
Syntax mac ieee-mac-addr
no mac
Context config>router>interface
Description
This command assigns a specific MAC address to an IP interface. Only one MAC address can be
assigned to an IP interface. When multiple
mac commands are entered, the last command overwrites
the previous command.
The no form of the command returns the MAC address of the IP interface to the default value.
Default IP interface has a system-assigned MAC address.
Parameters ieee-mac-addr — Specifies the 48-bit MAC address for the IP interface in the form aa:bb:cc:dd:ee:ff
or aa-bb-cc-dd-ee-ff, where aa , bb , cc , dd , ee and ff are hexadecimal numbers. Allowed values
are any non-broadcast, non-multicast MAC and non-IEEE reserved MAC addresses.
multihoming
Syntax [ no ] multihoming primary|secondary [ hold-time holdover-time ]
