Step 1 |
switch#
configure
terminal
|
Enters global
configuration mode.
|
Step 2 |
switch(config)#
ip lisp etr
|
Configures a
Cisco NX-OS device to act as an IPv4 Locator/ID Separation Protocol (LISP)
Egress Tunnel Router (ETR),
|
Step 3 |
(Optional) switch(config)#
vrf context
vrf-name
|
(Optional)
Creates a new VRF and enters VRF configuration mode to configure
the first-hop router (FHR) function within the specified VRF routing context
instead of using the default VRF.
The value of the
vrf- name is any case-sensitive,
alphanumeric string of up to 32 characters.
Note
|
This approach implements a mobility design where each mobile
VLAN is a member of a distinct VRF and an external site gateway xTR acts as
router for all of the mobile VLANs (VRFs).
|
|
Step 4 |
switch(config)#
lisp dynamic-eid
dynamic-EID-policy-name
|
Configures a
LISP Virtual Machine (VM) Mobility (dynamic-EID roaming) policy and enters the
LISP dynamic-EID configuration mode.
|
Step 5 |
switch(config-lisp-dynamic-eid)#
database-mapping
dynamic-EID-prefix locator
priority
priority
weight
weight
|
Configures a
IPv4 or IPv6 dynamic-endpoint identifier to Routing Locator (EID-to-RLOC)
mapping relationship and its associated traffic policy.
Note
|
If you configured the
vrf context command, the IP prefix
specified for the
dynamic-EID-prefix locator argument
must belong to a local interface that is member of the same VRF.
|
|
Step 6 |
(Optional) switch(config-lisp-dynamic-eid)#
instance-id
iid
|
(Optional)
Configures an association between the dynamic EID policy and a
LISP Instance ID.
The
iid must match the instance ID configured
on the gateway xTR. The range is from 1 to 16777215. The default value is 0.
|
Step 7 |
switch(config-lisp-dynamic-eid)#
eid-notify ip-address key password
|
Enables
sending of dynamic endpoint identifier (EID) presence notifications to a
gateway xTR with the specified IP address along with the authentication key
used with the gateway xTR.
|
Step 8 |
switch(config-lisp-dynamic-eid)#
map-notify-group
ipv4-group-address
|
Configures a
discovering LISP-Virtual Machine (VM) switch to send a Map-Notify message to
other LISP-VM switches within the same data center site so that they can also
determine the location of the dynamic-EID.
|
Step 9 |
Repeat the
preceding steps for each first-hop device to be configured.
|
|
Step 10 |
switch(config-lisp-dynamic-eid)#
exit
|
Exits the LISP
dynamic-EID configuration mode and returns to global configuration mode.
|
Step 11 |
switch
(config)#
interface vlanvlan-id
|
Creates or
modifies a VLAN and enters interface configuration mode.
|
Step 12 |
(Optional) switch(config)#
vrf member
vrf-name
|
(Optional)
This step is required if you configured the
vrf context command.
Adds the interface being configured to a VRF when the FHR is
configured within a VRF context.
|
Step 13 |
switch(config-if)#
lisp mobility
dynamic-EID-policy-name
|
Configures an
interface on an Ingress Tunnel Router (ITR) to participate in Locator/ID
Separation Protocol (LISP) virtual machine (VM)-mobility (dynamic-EID roaming)
for the referenced dynamic-EID policy.
|
Step 14 |
switch(config-if)#
lisp-extended
subnet-mode
|
Configures an
interface to create a dynamic-endpoint identifier (EID) state for hosts
attached on their own subnet in order to track the movement of EIDs from one
part of the subnet to another part of the same subnet.
|
Step 15 |
switch(config-if)#
ip router ospf
instance-tag
area
area-id
|
Species the
Open Shortest Path First (OSPF) instance and area for an interface
|
Step 16 |
switch(config-if)#
ip ospf
passive-interface
|
Suppresses
Open Shortest Path First (OSPF) routing updates on an interface to avoid
establishing adjacency over the LAN extension.
|
Step 17 |
switch(config-if)#
hsrp
group-number
|
Enters Hot
Standby Router Protocol (HSRP) configuration mode and creates an HSRP group.
|
Step 18 |
switch(config-if-hsrp)#
ip address
ip-address
|
Creates a
virtual IP address for the HSRP group. The IP address must be in the same
subnet as the interface IP address.
|
Step 19 |
Repeat the
preceding steps for each interface to be configured for multihop mobility.
|
|
Step 20 |
switch(config-if-hsrp)#
end
|
Returns to
privileged EXEC mode.
