How to add IP route(s) So Kubernetes cluster addresses go via through appropriate adapter - kubernetes

Question

I have installed Kubernetes cluster(one Master and one Worker- Node) on CentOS-8 OS stand-alone server separately as per the below link instructions.
https://www.tecmint.com/install-a-kubernetes-cluster-on-centos-8/
Weave-Net - CNI plugin installed as per above link. Now I can see below new network adapter in our K8s Master & Worker-Node server.
weave: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1376
inet 10.32.0.1 netmask 255.240.0.0 broadcast 10.47.255.255
inet6 fe80::a07d:21ff:fef1:4656 prefixlen 64 scopeid 0x20<link>

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 48 bytes 4896 (4.7 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
But the problem is from host server unable to ping (Or) access any of our remote site/location IPs (ping response given below). whereas Local IPs are pinging & accessible.
ping -c 4 120.121.5.48
PING 120.121.5.48 (120.121.5.48) 56(84) bytes of data.

Also from host server tried to connect our remote LDAP server through telnet it shows below error message.
# telnet 120.121.5.48 389
Trying 120.121.5.48...
telnet: connect to address 120.121.5.48: No route to host
In our K8s Master & Worker-Node server have 23 network adapters, Statically network IP have configured, So any additional configuration need to be configured for K8s CNI reachable in default routing?
ip route show & route -n output as follows.
# ip route show

Tried to change the weave route to default with below command. it executed successfully, But still same problem.
ip route add 10.32.0.0/24 via 45.46.47.1 dev ens1f0 metric 100
Suppose if i run ifconfig weave down everything is working fine. But to use Kubernetes cluster i need Weave-net network adapter. So please help me to add IP route(s) So that my Kubernetes cluster addresses go via through appropriate adapter, So that i will be able to access both our local & remote location server.

I have changed the CNI-Weave-Net plugin to Flannel, now it is working as excepted.
