eBGP load balancing with single-homed BGP environment

eBGP load balancing :

[boxads]Today i will discuss how to configure eBGP load balancing with single-homed BGP environment. So lets go…….. If we look our topology we see here two ISP router are connected through two link.  Also this two router are in different autonomous system. Router R1 autonomous system is 21 & Router R2 autonomous system is 22.

Router R1 loopback address: 1.1.1.1  & 11.11.11.11

Router R2 loopback address: 2.2.2.2 & 12.12.12.12

Also this loopback0 are connected via static route & loopback1 connected via eBGP.

This scenario shows how to achieve load balancing when there are multiple (up to a maximum of six), equal-cost links. The links are terminated in one router at a local autonomous system (AS) and in another router at a remote AS in a single-homed BGP environment. Now we will be start our configuration part.

Router R1 Configuration:

Basic IP Configure:

R1#configure terminal
R1(config)#interface loopback 0
R1(config-if)#ip address 1.1.1.1 255.255.255.255
R1(config)#interface loopback 1
R1(config-if)#ip address 11.11.11.11 255.255.255.0
R1(config-if)#int fa0/0
R1(config-if)#ip address 10.10.0.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#int fa0/1
R1(config-if)#ip address 10.10.1.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#

How to display ONT info in Huawei OLT:

Here i will show you how to display ONT info by bellow command……….

[boxads]

At first go to interface mode then type display ont info  ONT id  Port id

look like bellow:

Huawei-OLT(config)#interface gpon 0/0

Huawei-OLT(config-if-gpon-0/0)#display ont info 6 0
—————————————————————————–
F/S/P                                 : 0/0/6
ONT-ID                             : 0
Control flag                       : active
Run state                           : online
Config state                       : normal
Match state                        : match
DBA type                            : SR
ONT distance(m)              : 1267
ONT battery state              : not support
Memory occupation          : –
CPU occupation                 : –

Display Service-port by Filtering Huawei OLT

by

How to see Service-port by Filtering Huawei OLT:

At first login your Huawei OLT and go to config mode. Then type service-port related bellow command.

[boxads]

Huawei-OLT(config)#display service-port all

It will show all service port by INDEX/Service-port wise in your OLT.

display service-port all

Huawei-OLT(config)#display service-port all sort-by port
