Configuration Examples for LISP Delegate Database Tree (DDT)

Examples: LISP Delegate Database Tree (DDT)

The following is an example of parent and child DDT nodes, where the parent has all of 10.0.0.0/8 and
delegates two sub-prefixes, 10.0.0.0/12 and 10.0.16.0/12 to two child DDT nodes. All of these prefixes are
within the DDT sub-tree Key-ID=0, IID=223, and AFI=1 (IPv4).
Switch(config)# lisp ddt authoritative-prefix instance-id 223 10.0.0.0/8
Switch(config)# lisp ddt child 192.168.1.100 instance-id 223 eid-prefix 10.0.0.0/12
Switch(config)# lisp ddt child 192.168.1.200 instance-id 223 eid-prefix 10.16.0.0/12
The following example defines the delegation of the EID-prefix 10.0.0.0/12 to a DDT Map Server with RLOC
192.168.1.100 and delegation of the EID-prefix 10.16.0.0/12 to a DDT Map-Server with RLOC 192.168.1.200.
The child DDT Map-Server for 10.16.0.0/12 is further configured to allow ETRs to register the sub-prefixes
10.18.0.0/16 and 10.17.0.0/16:
Switch(config)# lisp ddt authoritative-prefix instance-id 223 eid-prefix 10.16.0.0/12
Switch(config)# lisp site site-1
Switch(config)#
Switch(config)# lisp site site-2
Switch(config)# eid-prefix 10.17.0.0/16 instance-id 223
Command or Action
Switch# show lisp ddt vrf vrf-1
show lisp ddt queue [eid-address | instance-id
iid {eid-address} | vrf vrf-name]
Example:
Switch# show lisp ddt queue 10.1.1.1
show lisp ddt referral-cache [eid-address |
instance-id iid {eid-address} | cache-entries
{vrf vrf-name} | vrf vrf-name]
Example:
Switch# show lisp ddt referral-cache
10.1.1.1
end
Example:
Switch# end
eid-prefix 10.18.0.0/16 instance-id 223
Configuration Examples for LISP Delegate Database Tree (DDT)
Purpose
LISP DDT. When vrf vrf-nameis specified,
information for VRF is displayed.
Displays the map-resolver's map-request
queue. If eid-address is specified, then only
the queue element for an EID being
map-requested is displayed
Displays the DDT referral cache stored in
map-resolvers. When the eid-address variable
is specified each cache entry that is less
specific than the eid-address variable will be
displayed.
