By using indirect next hops, if a topology change occurs in the network, only the
indirect next hop is modified in the routing table, decreasing the number of state
changes required to achieve convergence.
Before You Configure IP
Before you configure IP, created lower-layer interfaces over which IP traffic flows.
For example, to configure an ATM interface:
host1(config)#
interface atm 1/0
host1(config-if)#
atm sonet stm-1
host1(config-if)#
no loopback
host1(config-if)#
atm clock internal chassis
host1(config-if)#
interface atm 1/0.10
host1(config-if)#
atm pvc 10 0 20 aal5snap
Refer to the appropriate chapters for information about configuring a specific type
of interface.
NOTE:
If you choose to configure VRRP, we recommend that you complete all IP
address configurations before you configure VRRP. See
JUNOSe Services Availability
Configuration Guide
, for additional information.
Creating a Profile
You can configure an IP interface dynamically by creating a profile. A profile is a set
of characteristics that acts as a pattern that can be dynamically assigned to an IP
interface. You can manage a large number of IP interfaces efficiently by creating a
profile with a specific set of characteristics. In addition, you can create a profile to
assign an IP interface to a virtual router.
A profile can contain one or more of the following characteristics:
■
access-route—Enables the creation of host access routes on an interface
■
address—Configures an IP address on an interface
■
auto-configure—Configures the interface for auto-configure mode
■
auto-detect—Configures the interface for auto-detect mode
■
directed-broadcast—Enables directed broadcast forwarding
■
filter-options-all—Enables filtering of packets with IP options on an interface
■
igmp—Configures an IGMP interface
■
ignore-df-bit—Specifies that the don’t-fragment bit is ignored
■
inactivity-timer—Configures inactivity time for IP interfaces
■
inspection—Associates an inspection list to the interface for firewalling
■
mtu—Configures the maximum transmission unit for a network
