protocol is at the core and which is at the boundary.
4) determines the route redistribution direction.
You can use the following command to reallocate route updates. This example is for OSPF ):
Router (config-router) # redistribute protocol [process-id] [metric-value] [metric-type-value] [subnets]
In this command:
◎ Protocol: Specifies the source route protocol for Route redistribution on the vro.

In fact, although their purpose is one: to allow users to access the site faster. But the principles of their application are vastly different.It must be clear to everyone that these are more common ways to host acceleration. So the text mainly introduc

Autonomous systems:(1) Autonomous system is connected by the homogeneous gateway of the Internet, autonomous system within the gateway to perform internal Gateway Protocol (IGP), mutual exchange of routing information(2) The IGP is dedicated within the autonomous system, serves for a particular application, is not valid outside the autonomous system;(3) An
manage the address of the route, just configured on the switch two metric values different default routes, so that can not meet the problem Please.
My understanding:
① two static routes on the switch
IP Route 10.50.13.80 255.255.255.240 10.10.45.4
IP Route 10.50.13.128 255.255.255.240 10.10.45.5
② also configures two static routes on R1, metric values are different, and configuration track
Track 1 interface ETHERNET0/2 Line-protocol
Track 2 interface ETHERNET0/3 Line-protocol
IP Route 1

Bridges Bridge: Network devices that connect two peer-to-peer networks, but in today's context, Linux Bridge is the famous Docker0.
BGP: Backbone network routing protocol, today with the Internet, the Internet is composed of many small autonomous networks, the three-tier routing between autonomous networks is implemented by BGP.

Data Packets transmitted in the MPLS network can have multiple labels. Generally, there is only one label for data transmission in the MPLS network, and there are two labels in the mpls vpn. This is the label stack, they are called the top label and the bottom stack label respectively. The inner layer label should be the bottom stack label, and the outer layer label is the top label. In any case, when packets are transmitted in the MPLS network, A vro forwards data only by looking at one label,
, the container above will assign it a globally unique IP address, which involves the topic of ipam.
Overlay: Build an independent network on top of an existing two-or three-layer network, which usually has its own independent IP address space, exchange, or routing implementation.
Ipsesc: A point-to-point encrypted communication protocol, typically used in the data channel of the overlay network.
VXLAN: This solution, proposed by a consortium of VMware, Cisco, Redhat, and so on, is the mos
with a unified management organization and a unified routing policy. The Routing Protocol adopted in the autonomous region is called the internal gateway protocol, which is commonly used by RIP and OSPF; the external gateway protocol is mainly used for routing selection between multiple autonomous domains, commonly used BGP and BGP-4 。
1. RIP Network Routing Protocol
The RIP Protocol was originally designe
protocols such as OSPF, Is-is, BGP, respectively, the calculation and maintenance of their own routing table, all the protocol generated routing entries eventually aggregated into a routing management module. For a given destination IP address, various routing protocols can compute a route. However, when the specific message forwarding using which protocol to calculate the route, then by the Routing management module according to a certain algorithm
through the process. When routing selection processes do not share information about the network system, it is called night routing (ships in night, SIN )。
3. Default seed measurement values. The default seed measurement values of RIP, IGRP, and VPN are all infinite. They do not enter the route selection table unless the default value is changed; the default IS-IS metric value IS 0, but it can enter the routing table. The default OSPF metric IS two types of LSA value 20, and the routing from

How does one achieve load balancing on multiple links?
Two methods:
1. Build an EBGP neighbor using the loopback port and use EBGP multi-hop
2. EBGP multipath
The following two methods are discussed:

3. Default seed measurement values. The default seed measurement values of RIP, IGRP, and VPN are all infinite.

public basic protocol for the Internet and mobile communication networks.
Although IPv6 standards originated in the Internet industry, in commercial sense, the mobile communication industry may be one of the earliest and largest beneficiaries. International Organization for Standardization (ISO), in addition to IETF's continued improvement of IPv6-related standards, 3GPP and ITU-T have also set up appropriate working groups to develop IPv6 protocol standards. Recently, IETF and 3GPP have jointl
