Configuring LISP ESM Multihop Mobility

The following example shows how to configure the first hop "FH-2a" in the sample topology:
ip lisp etr
lisp dynamic-eid VLAN-11
database-mapping 10.1.1.0/24 172.17.2.2 pr 10 w 50
database-mapping 10.1.1.0/24 172.17.2.3 pr 10 w 50
eid-notify 172.17.0.1 key 3 6d018260cf71b07c
map-notify-group 225.1.1.1
lisp dynamic-eid VLAN-12
database-mapping 10.1.2.0/24 172.17.2.2 pr 10 w 50
database-mapping 10.1.2.0/24 172.17.2.3 pr 10 w 50
eid-notify 172.17.0.1 key 3 6d018260cf71b07c
map-notify-group 225.1.1.2
interface Vlan11
lisp mobility VLAN-11
lisp extended-subnet-mode
ip address 10.1.1.4/24
ip ospf passive-interface
ip router ospf 100 area 0.0.0.2
hsrp 1
ip 10.1.1.1
interface Vlan12
lisp mobility VLAN-12
lisp extended-subnet-mode
ip address 10.1.2.4/24
ip ospf passive-interface
ip router ospf 100 area 0.0.0.2
hsrp 2
ip 10.1.2.1
The following additional configuration ensures that the FHRs can route traffic from other attached subnets to
servers that belong to the mobile subnet site1 and are discovered in the opposite data center. For this purpose
the FHRs are configured to establish an adjacency over a dedicated extended VLAN using a dedicated routing
protocol instance and to redistribute host routes from LISP.
For FH-1a:
ip prefix-list DiscoveredServers seq 5 permit 10.1.0.0/22 ge 32
route-map LISP2EIGRP permit 10
match ip address prefix-list DiscoveredServers
interface Vlan100
no shutdown
ip address 10.255.0.1/30
ip router eigrp 100
router eigrp 100
autonomous-system 100
redistribute lisp route-map LISP2EIGRP
For FHA-2a:
ip prefix-list DiscoveredServers seq 5 permit 10.1.0.0/22 ge 32
route-map LISP2EIGRP permit 10
match ip address prefix-list DiscoveredServers
