Configuring IP Exterior Gateway Protocols (BGP and EGP)
A-32
308628-14.00 Rev 00
Parameter: MTU Discovery
Path: Configuration Manager > Protocols > IP > Interfaces
Default: Disabled
Options: Enabled
|
Disabled
Function: Specifies whether the Reply MTU option (option 11 in RFC 1063) is enabled on
this interface. When the option is enabled, this interface responds to Probe
MTUs (option 12 in RFC 1063). A probe MTU requests the minimum MTU
(maximum transmission unit) of all networks an IP datagram must traverse from
source to destination. By enabling this interface to respond to probe MTUs, you
eliminate transit fragmentation and destination reassembly for datagrams
destined for this interface and, therefore, decrease network load.
Instructions: Select Enabled to enable the Reply MTU option on this interface; select
Disabled to disable the option on this interface.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.1.24.1.12
Parameter: AMR
Path: Configuration Manager > Protocols > IP > Interfaces
Default: Disabled
Options: Enabled
|
Disabled
Function: Specifies whether this interface generates ICMP (Internet Control Message
Protocol) address-mask reply (AMR) messages in response to valid
address-mask request messages. The interface generates ICMP address-mask
reply messages in compliance with the relevant sections of RFCs 950 and 1009.
Instructions: Select Enabled to enable ICMP address-mask reply message generation on this
interface. Select Disabled to disable ICMP address-mask reply message
generation on this interface.
