Objective:
‧ Configure EIGRP on a router
‧ Configure Label Distribution Protocol on a router
‧ Change the size of the Maximum Transmission Unit (MTU)
‧ Verify MPLS behavior
Scenario:
In this lab, you will configure a simple Enhanced Interior Gateway Routing Protocol (EIGRP) network to route IP packets. You will run Multiprotocol Label Switching (MPLS) over the IP internetwork to fast-switch Layer 2 frames.
Basic Configuration:
enable
configure terminal
!
no ip domain lookup
!
line console 0
logging synchronous
exec-timeout 0 0
!
host R*
Step 1: Configure Addressing
R1:
interface Loopback0
ip address 172.16.1.1 255.255.255.0
!
interface fastEthernet 0/0
ip address 172.16.12.1 255.255.255.0
no shutdown
R2:
interface fastEthernet 0/0
ip address 172.16.12.2 255.255.255.0
no shutdown
!
interface Serial1/0
ip address 172.16.23.2 255.255.255.0
clock rate 64000
no shutdown
R3:
interface Loopback0
ip address 172.16.3.1 255.255.255.0
!
interface Serial0/0
ip address 172.16.23.3 255.255.255.0
no shutdown
Step 2: Configure EIGRP AS 1
R1 & R2 & R3
router eigrp 1
network 172.16.0.0
no auto-summary
Step 3: Observe CEF Operation
R1:
show ip cef
show ip cef non-recursive
CEF should be enabled by default. If CEF is not enabled,
R1 & R2 & R3:
ip cef
Step 4: Enable MPLS on All Physical Interfaces
R1:
interface FastEthernet0/0
mpls ip
R2:
interface FastEthernet0/0
mpls ip
!
interface Serial1/0
mpls ip
R3:
interface Serial1/0
mpls ip
Step 5: Verify MPLS Configuration
R1-3:
show mpls interfaces
show mpls ldp discovery
show mpls ldp neighbor
show mpls ldp bindings
R1#show mpls ldp bindings
tib entry: 172.16.1.0/24, rev 6
local binding: tag: imp-null
remote binding: tsr: 172.16.23.2:0, tag: 16
tib entry: 172.16.3.0/24, rev 8
local binding: tag: 17
remote binding: tsr: 172.16.23.2:0, tag: 17
tib entry: 172.16.12.0/24, rev 4
local binding: tag: imp-null
remote binding: tsr: 172.16.23.2:0, tag: imp-null
tib entry: 172.16.23.0/24, rev 2
local binding: tag: 16
remote binding: tsr: 172.16.23.2:0, tag: imp-null
R1#traceroute 172.16.3.1
Type escape sequence to abort.
Tracing the route to 172.16.3.1
1 172.16.12.2 [MPLS: Label 17 Exp 0] 4 msec 24 msec 8 msec
2 172.16.23.3 8 msec * 8 msec
Step 6: Change MPLS MTU
R1-2:
show mpls interfaces fastEthernet 0/0 detail
Interface FastEthernet0/0:
IP labeling enabled (ldp):
Interface config
LSP Tunnel labeling not enabled
BGP tagging not enabled
Tagging operational
Fast Switching Vectors:
IP to MPLS Fast Switching Vector
MPLS Turbo Vector
MTU = 1500
R1-2:
interface fastEthernet 0/0
mpls mtu 1508
