Redistribution of RIB Routes into LISP
Example: Redistribution of RIB Routes in LISP
Figure 28: Redistribute RIB Routes into Map-cache Topology
xTR2 Configuration for RIB Route Redistribution into Map-cache
The following example shows how to configure the xTR2 in the sample topology for the LISP route map-cache
application:
switch# configure terminal
switch(config)# vrf context VRF1
switch(config-vrf)# ip lisp itr
switch(config-vrf)# ip lisp etr
switch(config-vrf)# instance-id 100
switch(config-vrf)# ip lisp locator-vrf default
switch(config-vrf)# ip lisp etr map-server 10.10.10.10 key lisp
switch(config-vrf)# ip lisp itr map-resolver 10.10.10.10
! Import fabric prefixes into lisp map-cache from BGP!
switch(config-vrf)# ip lisp route-import map-cache bgp 65536 route-map RM_BGP_to_LISP
Verifying Map-cache with RIB Route Redistribution
The following example displays the sample show command outputs for the map-cache route import
configurations:
xTR2# show ip lisp map-cache vrf VRF1
LISP IP Mapping Cache for VRF "VRF1" (iid 100), 1 entries
* = Locator data counters are cumulative across all EID-prefixes
192.168.1.0/24, uptime: 00:09:42, expires: 0.000000, via route-import
Producer Set: 0004 route_import
Negative cache entry, action: send-map-request
Once a prefix is imported as a map-cache, the routing table shows how LISP takes over the prefix to ensure
an optimized path through the LISP overlay to the destination device.
xTR2# show ip route 192.168.2.2 vrf VRF1
IP Route Table for VRF "VRF1"
'*' denotes best ucast next-hop
