Configuring a VLAN Dynamic Profile That Associates VLAN Interfaces with Separate Routing Instances
You can configure a VLAN dynamic profile that dynamically creates underlying VLAN interfaces and associates these interfaces with dynamically created routing instances. The VLAN interface is created in the default logical system (LS) for a specific routing instance as defined by VSA 26–1 (Virtual-Router) on the AAA server (for example, RADIUS server).
To configure a dynamic VLAN profile using routing instances:
- Name the profile.[edit]user@host# edit dynamic-profiles VLAN_PROFILE_RI
- Specify that you want to dynamically create routing instances
on the default logical system.[edit dynamic-profiles VLAN_PROFILE_RI]user@host# edit routing-instances $junos-routing-instance
- Define the routing instance interface statement
with the internal $junos-interface-name variable used by
the router to match the interface name of the receiving interface.[edit dynamic-profiles VLAN_PROFILE_RI routing-instances “$junos-routing-instance”]user@host# set interface $junos-interface-name
- Define the dynamic profile interfaces statement
with the internal $junos-interface-ifd-name variable.[edit dynamic-profiles VLAN_PROFILE_RI]user@host# edit interfaces $junos-interface-ifd-name
- Define the unit statement with the internal $junos-interface-unit variable used by the router to generate
a unit value for the interface.[edit dynamic-profiles VLAN_PROFILE_RI interfaces "$junos-interface-ifd-name"]user@host# edit unit $junos-interface-unit
- To support dynamic demux interfaces, enable them using
the demux-source statement.
- For IPv4 demux interfaces, specify inet as the
source type.[edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set demux-source inet
- For IPv6 demux interfaces, specify inet6 as the
source type.[edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set demux-source inet6
- For IPv4 demux interfaces, specify inet as the
source type.
- (Optional) To configure the router to respond to any ARP
request, specify the proxy-arp statement.[edit dynamic-profiles VLAN_PROFILE_RI interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set proxy-arp
- Specify that you want to use dynamic VLAN IDs in the dynamic
profile.[edit dynamic-profiles VLAN_PROFILE_RI interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set vlan-id $junos-vlan-id
The variable is dynamically replaced with both the TPID value and a VLAN ID within the VLAN range specified at the [interfaces] hierarchy level.
- Define the unit family type.
- For IPv4 interfaces, specify the inet family
type.[edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set family inet
- For IPv6 interfaces, specify the inet6 family
type.[edit dynamic-profiles VLAN-PROF1 interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit"]user@host# set family inet6
- For IPv4 interfaces, specify the inet family
type.
- (Optional) Enable IP and MAC address validation for dynamic
demux interfaces in a dynamic profile.[edit dynamic-profiles VLAN_PROFILE_RI interfaces "$junos-interface-ifd-name" unit "$junos-interface-unit" family inet]user@host# set mac-validate loose
- Specify the unnumbered address to dynamically create loopback
interfaces.
Note: You can optionally specify the preferred source address. This option is included in the step.
