Why does my router Ping across two networks?
Router already knows hoe to reach the two networks, ´cause it have directly connected. You need to have routing set up on the routers so that every router which is on the networks of the two hosts knows how to reach the other network. This would work if each host’s gateway was Router1, but that may not always be the case.
Is it safe to run a routing protocol on a router?
Running a routing protocol on the routers on the same network where hosts are connected creates security implications. This can provide valuable information to an attacker (internal or external on compromised resource) about the network topography and subnets in use. Additional steps would be required to secure this.
Can a router automatically respond to network changes?
You can do this dynamically with a routing protocol, or statically with static routes configured in the routers. Static routing doesn’t scale, and it can’t automatically respond to changes in the network. Does host 1 have a default route via router 1, or a specific route to host 2’s network via router 1?
Why does my router not respond to ICMP redirects?
Generally turned off on routers and hosts are often configured to not respond to ICMP redirects. You would need to make sure it was enabled on all devices. Let the routers do the work without ICMP redirects.
How to Ping between different subnets across a link-network?
All other addresses are unreachable to him, since no gateway is defined. To make the two PCs be able to ping each other without adding a router or changing the IPs, you’d need to change the network masks to 0. So PC1 will be 10.10.10.1/0 and PC2 will be 192.168.1.1/0, making the subnet range for both of them the same 0.0.0.0-255.255.255.255
Is it possible to Ping two VLANs at once?
PROBLEM: All vlans can ping to each other except for vlan 300. Maximum ports are on vlan 100 and some are on other VLANs. Interface 7/1, 7/2 are on vlan 300. Config of 7/1 adn 7/2 is:
