Description
Advanced Routing Protocols
Border Gateway Protocol (BGP) is a routing protocol used to exchange routing information between routers in different autonomous systems (AS) on the Internet. It is considered to be the most advanced routing protocol and is typically used by service providers to connect multiple networks together.
Open Shortest Path First (OSPF) is a routing protocol used primarily in IP networks. It is considered a link state protocol, meaning that it builds a map of the entire network and calculates the shortest path to a destination based on the state of the links in the network. OSPF is a classless routing protocol, meaning that it supports variable-length subnet masks (VLSMs), which allows for more efficient use of IP address space.
Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco proprietary protocol that is considered to be a hybrid of a distance-vector and a link-state routing protocol. It uses metrics such as bandwidth, delay, reliability, and load to calculate the best path to a destination. EIGRP supports VLSMs and also has advanced features such as unequal cost load balancing and fast convergence.
Routing Information Protocol (RIP) is a distance-vector routing protocol, which means that it uses hop count as a metric to determine the best path to a destination. it’s considered a simpler routing protocol and is typically used in smaller networks.
Survivable Remote Site Telephony (SRST) is Cisco proprietary protocol which is used to provide telephony services in the event of a WAN outage. It allows for the continued operation of Cisco IP phones and PBX systems at remote sites by using the local router as a fallback call-processing agent. SRST also allows for the configuration of call routing and voicemail services at the remote site.
Network Security and Threat Defense Capalities
The C2911-CME-SRST/K9 Cisco 2911 Router Voice Bundle with Packet Voice DSP Module has a variety of network security and threat defense capabilities built-in. Some of these include:
- Firewall features: The router includes an integrated firewall that can be used to secure traffic passing through the network. The firewall can be configured to allow or block specific types of traffic, such as IP addresses, ports, or protocols.
- Virtual Private Network (VPN) support: The router supports VPNs, which allow for secure remote access to the network. This can be used to protect data and voice traffic passing between remote sites, as well as between remote users and the network.
- Intrusion Prevention System (IPS): The router includes an IPS feature that can be used to detect and prevent malicious traffic from entering the network. The IPS uses a signature-based approach to identify known threats and can also be configured to look for specific types of traffic or behavior that may indicate an attack.
- Access Control Lists (ACLs): The router supports the use of ACLs, which can be used to control access to specific resources on the network. This can be used to restrict access to specific IP addresses, ports, or protocols.
- Quality of Service (QoS): The router supports QoS, which can be used to prioritize different types of network traffic. This can be used to ensure that critical voice and video traffic is given priority over less-critical data traffic.
- Packet Voice DSP (Digital Signal Processor) Module: The router is equipped with a Packet Voice DSP Module, which provides advanced voice processing capabilities such as echo cancellation and noise reduction.
- VPN support: The router supports VPNs, which allow for secure remote access to the network. This can be used to protect data and voice traffic passing between remote sites, as well as between remote users and the network.
Establishing Internet Connectivity
Establishing Internet connectivity on the C2911-CME-SRST/K9 Cisco 2911 Router Voice Bundle with Packet Voice DSP Module can be done by configuring the router’s WAN interface with the appropriate settings for the connection type being used. Some of the common steps to establish Internet connectivity would be:
- Configure the WAN interface: The WAN interface on the router will need to be configured with the appropriate settings for the connection type being used. This can include IP address, subnet mask, default gateway, and DNS server information.
- Configure the routing protocol: The router will need to be configured with a routing protocol that is compatible with the WAN connection being used. Common routing protocols include Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), and Routing Information Protocol (RIP).
- Configure access control lists (ACLs): Access control lists (ACLs) can be used to control access to specific resources on the network. This can be used to restrict access to specific IP addresses, ports, or protocols.
- Configure security features: The router’s built-in security features can be configured to protect the network from external threats. This can include configuring a firewall, virtual private network (VPN) support, intrusion prevention system (IPS) and Quality of Service (QoS).
- Verify the connectivity: To verify that the Internet connectivity is established, test the connectivity by pinging a public IP address or a well-known website. Also, you can use the “show ip interface” command to check the status of the WAN interface and the “show ip route” command to check the routing table.
